We want to enrich pretraining with a large, +diverse bank of **georeferenced ground-truth label rasters** ("open-set segmentation" +data) that can be paired with that imagery at training time. The labels come from ~300 +candidate datasets catalogued in +`data/open_set_segmentation_datasets.json` +(32 already on local disk as rslearn datasets, 268 external). Targets are a mix of +**per-pixel classification** (crop type, land cover, tree species, …) and **per-pixel +regression** (canopy height, biomass, soil properties, fractional cover, population, +nightlights, bathymetry, …). + +The immediate goal is to assemble, per dataset, **up to 1000 locations per class** +(classification) or **up to 5000 locations** (regression), each stored as a small +single-band GeoTIFF label patch plus sidecar metadata, so labels can later be co-located +with pretraining imagery by geography and time overlap. + +**This document is the task spec.** It is written to be loaded into a fresh agent (with no +memory of the planning session) together with a single dataset's manifest entry.

Registry (`registry.json`) + +`data/open_set_segmentation_data/registry.json` (in the +repo, version-controlled) is the canonical map from manifest `name` → on-disk `slug`, plus +per-dataset status. It is +generated from the manifest with slugs already assigned (uniqueness enforced) — **use the +slug the registry gives you; do not re-derive it.** Each entry: +```json +{"name": "VIIRS Nightfire Gas Flaring", "slug": "viirs_nightfire_gas_flaring", + "source": "...", "family": "...", "label_type": "...", "have_locally": false, + "status": "pending", "task_type": null, "num_samples": null, "notes": ""} +``` +`status` lifecycle: `pending` → `selected` (queued for work) → `in_progress` → +`completed` | `rejected` | `temporary_failure`. The registry — not the manifest — is the +source of truth for what slug a dataset uses. + +**`rejected` vs `temporary_failure` — pick the right terminal status:** +- `rejected` = the dataset **cannot be used as-is** for a fundamental reason (no + recoverable geocoordinates, all labels pre-2016, phenomenon not observable at 10–30 m, + label semantics not expressible as per-pixel class/regression, license forbids use). Do + not expect to retry these without new information. +- `temporary_failure` = the dataset **is a good fit and would process, but an external + transient problem blocked it right now** — source server outage / HTTP 5xx, rate-limit, + temporary infra failure, or a flaky mirror. These are **retry candidates**: re-running + the same script later (once the source recovers) should succeed. Put the concrete failure + and retry steps in `notes` and in the summary. (Datasets blocked only on missing + credentials use `rejected` with `notes: "needs-credential: "` as before — the user + supplies creds/pre-downloaded copies out of band; use `temporary_failure` specifically + for transient source/infra errors, not for permanent access gates.) + +**CRITICAL — do NOT write the central `registry.json`.** It is owned solely by the +orchestrator. Many dataset scripts run concurrently, and direct writes to the shared file +corrupt it. Instead, record your status in your OWN per-dataset file +`datasets/{slug}/registry_entry.json` by calling +`manifest.write_registry_entry(slug, status, task_type=, num_samples=, notes=)` (the older +name `manifest.update_status` is an alias and is also safe — both write only the +per-dataset entry, never the central registry). Write it when you start (`in_progress`) +and when you finish (`completed` with `task_type`/`num_samples`, or `rejected` with the +reason in `notes`). The orchestrator periodically runs `manifest.aggregate_registry()` to +merge every per-dataset `registry_entry.json` (read from weka `datasets/{slug}/`) into the +central `registry.json` (in the repo), and backs the central file up to `registry.json.bak` +before launching any batch of agents. Rejected datasets still get a +`datasets/{slug}/registry_entry.json` (the one file they write to weka). + +## 2. GeoTIFF spec (the label patch) + +**When to write a GeoTIFF vs a point table:** GeoTIFFs are for labels **larger than a +single pixel** — dense rasters, rasterized polygons, and detection tiles (≥ a few px). +**Pure sparse-point datasets (1×1 labels) are NOT written as per-sample GeoTIFFs** — a 1×1 +label is just a (location, class-or-value) pair, and writing millions of tiny files +cripples weka. Point-only datasets use one dataset-wide GeoJSON table instead (see §2a). The +rest of this section (§2) applies to the GeoTIFF case. + +- **Single band**, **local UTM** projection, **10 m/pixel**, north-up (positive + `x_resolution`, negative `y_resolution`). Pick the UTM zone from the sample's lon/lat via + `rslearn.utils.get_utm_ups_crs.get_utm_ups_projection(lon, lat, 10, -10)`, or reuse the + source window's CRS if already UTM at 10 m. +- **Size**: target **64×64**, hard cap 64×64. Size down to the label's real footprint — + natively-small dense products at their native extent (e.g. WorldCover ≈ 10×10), sparse + point labels → **1×1**. Never exceed 64 on either axis. +- **dtype + nodata**: + - Classification → **uint8**. Class IDs start at **0**; value **255 = nodata/ignore** + (unobserved pixels, detection buffers). If a dataset has an explicit + background/negative class, it is a normal class ID (commonly 0). + - Regression → dtype matching the source (**float32** default; int16/uint16 when the + source is integer-valued and range fits). Nodata sentinel default **-99999** (repo's + `MISSING_VALUE`); may override per dataset — record the chosen value in + `metadata.json`. +- Write with rslearn so georeferencing is exact: + `GeotiffRasterFormat().encode_raster(path_parent, Projection(crs, 10, -10), pixel_bounds, + RasterArray(chw_array=arr[np.newaxis]), fname=...)` where `pixel_bounds` is + `(col*W... )` integer pixel coords under that projection. Write atomically (`.tmp` then + rename), as in the download template. + +## 2a. Point-table format (sparse-point datasets only) — GeoJSON + +For pure sparse-point datasets (each label is a single 10 m pixel with a class id or a +regression value), do **NOT** create `locations/{id}.tif` or per-point JSONs. Instead +write **one** dataset-wide **GeoJSON** table `datasets/{DATASET}/points.geojson`: a +`FeatureCollection` with one `Point` `Feature` per location. Coordinates are WGS84 +`[lon, lat]` (GeoJSON's native CRS); pretraining projects them onto the S2 grid. Per-point +fields (`id`, `label`, `time_range`, `change_time`, `pre_time_range`, `post_time_range`, +`source_id`) live in each feature's +`properties`; `dataset`/`task_type`/`count` are FeatureCollection-level foreign members. +Change/event point datasets set `pre_time_range`/`post_time_range` and leave `time_range` +null, exactly as for GeoTIFF samples (§3, §5). +```json +{ + "type": "FeatureCollection", + "dataset": "olmoearth_lcmap_land_use", + "task_type": "classification", // or "regression" + "count": 5643, + "features": [ + {"type": "Feature", + "geometry": {"type": "Point", "coordinates": [-106.3927, 43.3233]}, + "properties": { + "id": "000000", + "label": 2, // class id (classification) OR value (regression) + "time_range": ["2017-01-01T00:00:00+00:00", "2018-01-01T00:00:00+00:00"], + "change_time": null, "pre_time_range": null, "post_time_range": null, + "source_id": "test/sample_10000"}} + ] +} +``` +`label` is the class id for classification or the numeric value for regression. The +dataset-level `metadata.json` (class map / regression block, §3) is still written. Use +`io.write_points_table(slug, task_type, points)` — it takes the same list of point dicts +(`id`/`lon`/`lat`/`label`/`time_range`/`change_time`/`source_id`, plus optional +`pre_time_range`/`post_time_range` for change datasets) and writes the GeoJSON. +A single `points.geojson` handles even large sets (e.g. 50k features) fine; there is no +JSON-lines variant. + +## 3. Metadata schemas + +`datasets/{DATASET}/metadata.json` (dataset-level): +```json +{ + "dataset": "olmoearth_kenya_nandi_crop_type", + "name": "OlmoEarth Kenya Nandi crop type", + "task_type": "classification", // or "regression" + "source": "olmoearth", "license": "internal", + "provenance": {"url": "...", "have_locally": true, "annotation_method": "..."}, + "sensors_relevant": ["sentinel2", "sentinel1", "landsat"], + + // classification only: id <-> name, plus optional per-class description from the source + "classes": [ + {"id": 0, "name": "Coffee", + "description": "Perennial Coffea shrub plots, incl. shade-grown smallholder coffee."}, + {"id": 1, "name": "Trees", "description": null} + ], + "nodata_value": 255, + + // regression only: what we are regressing (name + optional description), plus range/dtype + "regression": { + "name": "canopy_height", + "description": "Top-of-canopy height from fused GEDI lidar + Sentinel-2 (Lang et al. 2023).", + "unit": "meters", "dtype": "float32", + "value_range": [0.0, 61.2], "nodata_value": -99999, + "buckets": [0, 5, 10, 20, 40] // optional, if bucket-balanced + }, + + "num_samples": 4231, + "notes": "..." +} +``` +Use `classes` for classification and `regression` for regression (never both). In +`classes`, `description` is optional — populate it with a detailed class definition when +the source dataset provides one (legend notes, codebook, taxonomy description); set to +`null`/omit when unavailable. In `regression`, `name` is required (a short identifier for +the regressed quantity, e.g. `canopy_height`, `soil_organic_carbon`, `population_density`) +and `description` is optional (a fuller definition of the quantity and how it was measured). + +`datasets/{DATASET}/locations/{SAMPLE_ID}.json` (per-sample; **GeoTIFF datasets only** — +point-only datasets put this info in the `points.geojson` feature `properties` instead, §2a): +```json +{ + "crs": "EPSG:32737", + "pixel_bounds": [29696, -964608, 29760, -964544], // integer px in crs, matches tif + "time_range": ["2024-01-01T00:00:00+00:00", "2024-12-31T00:00:00+00:00"], + "change_time": null, // ISO time if a change/event label (see §5) + "pre_time_range": null, // change datasets only: 6-mo "before" window (see §5) + "post_time_range": null, // change datasets only: 6-mo "after" window (see §5) + "source_id": "sample_951", // provenance back to source record, optional + "classes_present": [0, 3] // optional convenience for classification +} +``` +Non-change labels set a single `time_range` (must be ≤ 1 year / 360 days) with +`pre_time_range`/`post_time_range` null. **Change/event labels (§5) instead set +`pre_time_range` and `post_time_range` (each ≤ 183 days) and leave `time_range` null** — the +two windows can be far apart, so no single ≤360-day span represents the sample; `change_time` +is retained as the reference event time. The GeoTIFF carries its own georeferencing; +`crs`/`pixel_bounds` are duplicated in JSON for convenience. + +## 4. Processing recipes by `label_type` + +- **points — sparse point segmentation** (the point carries a class, possibly a + background/negative class; e.g. crop-type points, land-cover reference points, tree + genus): **write to the GeoJSON point table (§2a), not GeoTIFFs.** One `Point` feature per + point: geometry `[lon, lat]`, `properties.label=class_id`, `time_range`, … Subject to §5 + balancing. Same for **regression points** (canopy height / soil / biomass at a point): one + feature per point with `properties.label=`. +- **points — object detection, positive-only** (the point marks presence, absence is + everywhere else; e.g. vessels, turbines, dams-as-points, mines-as-points). **Two cases — + pick by where the negatives come from:** + - **(a) Global point inventory** (an isolated list of object coordinates — turbine/dam/ + platform/mine/volcano databases — with NO real annotated scene): emit each detection as a + **presence-only point** in the dataset-wide `points.geojson` (§2a): one `Point` feature, + `label` = object class id (multi-class where the source distinguishes types), a static + 1-year `time_range`, `change_time` = null. Do **NOT** fabricate a background/buffer or + synthetic negative tiles — there is no real observed absence to encode; the assembly step + supplies negatives by sampling other datasets (§5). This is the **default** for object + point inventories. + - **(b) Exhaustively-searched real scene** (the detections were annotated within an actual + image/window that was searched end-to-end, so object-free area is a *genuine observed* + negative — e.g. SAR/optical vessel scenes, xView3, annotated marine-infrastructure or + wind-turbine windows): keep the **tunable detection encoding** — a positive square + (default 1×1, or object-sized) at the detection, a **nodata (255) buffer ring** around it, + **background (0)** filling the rest of a context tile (default 32×32, ≤64). **Buffer ≥10 px** + (default `buffer_size=10`): coordinates are rarely pixel-exact, so a thick ignore ring + avoids penalizing a few-pixel offset (positive_size=1, buffer_size=10 → a 21×21 ignore + region, still ample background in a 32×32/64×64 tile). Expose `positive_size`, + `buffer_size`, `tile_size`; also emit background-only negative tiles drawn from the same + exhaustively-searched scenes so the class has real negatives. Use `encode_detection_tile`. +- **polygons**: rasterize each polygon (or sampled sub-windows for large/dense coverage) + into a ≤64×64 UTM tile at 10 m via `rasterio.features.rasterize` (transform built from + pixel bounds + resolution; see seagrass ref). Value = class ID; outside-polygon = + background or nodata per dataset semantics. Balance per §5. +- **dense_raster**: crop ≤64×64 windows from the source raster (reproject to UTM 10 m if + needed). Use **tiles-per-class balanced** sampling. For **derived-product maps**, prefer + spatially-homogeneous / high-confidence windows (e.g. windows where the class occupies a + strong majority, or that pass the product's confidence layer). + - **VHR-native labels** (sub-metre / aerial, e.g. Maldives at 0.35 m, OpenEarthMap, + LoveDA, FLAIR): **resample the label to 10 m** and **tile** the (often >640 m) source + into ≤64×64 patches. Use **mode/nearest** resampling for categorical labels (never + bilinear) — `read_label_raster` with a 10 m projection reprojects via WarpedVRT, so + pass a nearest/mode resampling. Before committing effort, judge suitability: some fine + VHR classes (individual buildings, narrow roads, fine coral/seagrass zonation) may be + unresolvable at 10 m — reject or coarsen the class set and note it. +- **bboxes / oriented boxes**: treat like detection (rasterize the box footprint as + positive, buffer, background). +- **lines** (roads, glacier fronts, faults, forest roads): rasterize the line to a mask + (small dilation so it's visible at 10 m); reject if the feature is not observable at + 10–30 m. +- **scene-level** (e.g. EuroSAT): emit a small uniform-class tile only if it is genuinely + a coherent land-cover patch; otherwise reject as patch-classification, not segmentation. + +## 5. Sampling, time range, and change labels + +**Handled at pretraining-assembly time — do NOT special-case per dataset.** Two concerns +are resolved downstream when the single combined pretraining dataset is assembled from all +these labels, so per-dataset agents should not work around them: +- **Positive-only / no-background datasets.** Some reference datasets have only foreground + classes and no background/negative class (presence points like hillforts/species; or + foreground-type masks like rock-glacier active/transitional/relict, glacier zones). Do + **not** fabricate synthetic negatives for these — leave non-object pixels as nodata/ignore + (255) and record every real class. The assembly step gives them negatives by sampling an + equal number of locations from *other* datasets. This now includes **object point + inventories** (turbines/dams/platforms/mines/volcanoes/…), which are emitted as + presence-only points with no fabricated negatives (§4 case (a)). The **only exception** is + **exhaustively-searched real-scene detection** (§4 case (b): vessel/xView3/annotated + infrastructure windows), which still emits its own `background`(0) + negative tiles because + those negatives are *genuinely observed* within the searched scene. + - **Assembly-time grouping (`assemble_classes.py`).** A dataset joins the shared + presence-only training group **only if** it is foreground-only (no negative/background + class) **and** has few classes (`PRESENCE_ONLY_MAX_CLASSES`, currently ≤3). Everything + else — many-class rich classifications (crop-type, land-cover, species, ecosystem, vessel- + type, commodity, mine-marker, …) and any dataset carrying its own negative class — becomes + its **own standalone multiclass training group** (self-contained softmax; no background is + fine). This keeps the small foreground detectors (dams, turbines, platforms, roads, …) + pooled while letting rich maps train by themselves, and it stops crop/water/land-cover + datasets from wrongly negating each other in the pool. + - **Concept merge/conflict for the pool + (`data/open_set_segmentation_data/presence_only_concepts.json`).** Pooled classes that + denote the *same* real-world thing across datasets are **merged** into one global class + (e.g. the wind-turbine detectors; the two road datasets). Classes whose concepts **overlap + / subsume** but aren't identical are flagged as mutual **conflicts** (e.g. individual + wind_turbine ↔ wind_farm; offshore oil/gas platform ↔ gas flare; mining ↔ tailings; a + generic rock_glacier ↔ its active/transitional/relict states) and excluded as each other's + negatives; disjoint concepts (wind turbine vs oil platform; maize vs wheat) stay normal + negatives. `assemble_classes` emits, in the `__presence_only__` group of + `class_mapping.json`, a `concepts` map and a `conflicts` adjacency per pooled global id. + Curate the concept file to add clusters; unmatched entries are surfaced by the assembler. +- **Rare classes.** The assembly step discards classes with fewer than a minimum sample + count when building the final dataset. So do **not** reject a dataset, or drop a class, + merely because some classes are sparse (even single-sample classes) — keep every class you + can, still honoring the 254-class uint8 cap and the top-254-by-frequency rule below. Note + sparse classes in the summary; downstream filtering removes the too-small ones. + +- **Per-dataset total cap: 25,000 samples (hard).** No dataset may exceed 25k label + samples. `sampling.MAX_SAMPLES_PER_DATASET = 25000`. (`geolifeclef_geoplant`, 50,800, + predates this cap and is grandfathered — do not use it as a precedent.) +- **Classification counts**: up to **1000 locations per class**, tiles-per-class balanced, + **subject to the 25k total** — when `n_classes × 1000 > 25000`, lower the per-class limit + to `25000 // n_classes` (this is what `balance_by_class(..., total_cap=25000)` does by + default). Prioritize rare classes so they reach the (possibly reduced) target; log any + truncation. +- **Large taxonomies & the 254-class cap**: classification labels are **uint8** (ids + 0–254, 255=nodata), so a dataset can have at most **254 classes**. When a source has more + (tree species, GlobalGeoTree ~21k, EuroCrops HCAT ~175 is fine, GeoLifeCLEF ~10k), + **keep the top 254 classes by frequency** (ids 0–253 in descending frequency), drop the + rest, and record the dropped count in the summary. (Do not switch to uint16.) +- **Multi-target / mixed-modality sources** (e.g. solar polygons + wind-turbine points; + buildings + damage levels): **combine into ONE dataset with a unified class scheme** + (e.g. background / solar_pv / wind_turbine), not separate per-target datasets. Segmentation + and detection targets can coexist in one class map; document the scheme in the summary. +- **Regression counts**: up to **5000 locations per dataset** (well under the 25k cap). + Bucket-balance across the value range only when the raw distribution is very skewed + (per-dataset judgment; record buckets in `metadata.json` if used). +- **Source splits**: if the source dataset has train/val/test splits, **use all of them** + (all windows are fair game as pretraining labels; no split filtering required). You may + record the source split in the sample JSON `source_id`/notes if convenient, but it is + not required. +- **Large global derived-product rasters** (WorldPop, JRC TMF, global crop/plantation + maps, etc.) with no in-situ reference alternative: **sample a bounded set of tiles** — + download only enough of the product to draw the target count (≤1000/class or ≤5000 + regression) from representative regions. Do not attempt global coverage. Document the + regions/sampling used in the summary. +- **Time range assignment**: + - Specific-image / specific-date labels (vessel positions, dated detections): **~1 hour** + (or the source image's acquisition time) — the label describes one image. + - Seasonal/annual labels (crop type, land cover, most maps): **1 year**, anchored on the + labeled year/season. If the valid period is longer than a year, **uniformly sample a + 1-year window** within it. + - Static labels (geology, lithology, persistent sites): pick a representative 1-year + window in the Sentinel era (2016+). +- **Change labels** (deforestation events, urban expansion, burn scars with a date, + bitemporal change-detection pairs, etc.): the label is a **mask of where** a change + occurred. Emit **two independent six-month observation windows**, `pre_time_range` + (a "before" window) and `post_time_range` (an "after" window), and **leave `time_range` + null**; keep `change_time` as the reference event time (may be null for cumulative masks). + Pretraining pairs a "before" image stack (sampled from `pre_time_range`) with an "after" + stack (from `post_time_range`) and probes on their difference. Build the windows with + `io.pre_post_time_ranges(change_time, gap_days=, pre_offset_days=)` and pass + `pre_time_range`/`post_time_range` to `io.write_sample_json` / the point dict: + - **The two windows need NOT be adjacent.** Place them to match what the source actually + compares, so the change reliably falls *between* them: + - **Single dated event** (fire ignition, quake, flood, dated alert): default **adjacent** + split at `change_time` (`gap_days=0`) — a 6-mo "before" and 6-mo "after". + - **`change_time` is a post-event acquisition** (the event precedes it, e.g. the + cloud-free post-fire scene): use `pre_offset_days` so the pre window ends before the + true event (burn scars ~90 d; rapid post-disaster imagery ~45 d). + - **Two-epoch / multi-year comparison** (bitemporal image pairs, pre-mosaic vs + post-mosaic years apart): center each window on its own acquisition period + (season-aligned), e.g. pre ≈ 6 mo around the earlier image, post ≈ 6 mo around the + later one — they may be several years apart. + - **Year-resolved or cumulative-span events** (annual GFC loss year; a cumulative + multi-year disturbance mask): put the ambiguous span **in the gap** — pre in a year + safely before it, post in a year safely after — so the exact timing no longer matters. + - Each window must be **≤ 183 days**. Anchor windows in the Sentinel era (post ≥ 2016); + drop or Landsat-note samples whose windows would fall entirely before it. + - **This replaces the old "reject if the change date is not resolvable to ~1-2 months" + rule.** Because the ambiguous span can sit in the gap between the two windows, coarsely- + timed changes (year-resolved, multi-year pre/post comparisons) are now **usable** — do + not reject them on timing grounds. (`oscd`, `olmoearth_land_cover_change`, `cam_forestnet`, + `olmoearth_forest_loss_driver`, and `bark_beetle` were previously rejected on that ground + and are now reprocessed under this scheme.) Still reject a change dataset only for the + usual independent reasons (no geocoordinates, all labels pre-2016, not observable at + 10-30 m, etc.). + - A **persistent post-change state** that stays visible long after the event (a burn scar, + a completed clear-cut, a filled reservoir) may alternatively be encoded as + **presence/state classification** with `change_time=null` and a single static-label + 1-year `time_range` (no pre/post) — use this when there is no meaningful "before" to pair, + and note the reasoning in the summary. + +## 6. Shared code module layout + +Under `olmoearth_pretrain/open_set_segmentation_data/` (in the repo). **These already +exist and are validated — import and reuse them; extend rather than duplicate.** Run +per-dataset scripts as `python3 -m +olmoearth_pretrain.open_set_segmentation_data.datasets.{slug}` from the repo root (plain +`python3` has rslearn available; `uv run` also works). +- `manifest.py` — `load_manifest()`, `load_registry()`, `slugify(name)`, `find_slug(name)`, + `get_entry(slug)`, `write_registry_entry(slug, status, task_type=, num_samples=, notes=)` + (writes per-dataset `registry_entry.json`; `update_status` is a back-compat alias), + `aggregate_registry()` (orchestrator-only: merge entries into central `registry.json`). +- `io.py` — `check_disk()`, `dataset_dir/locations_dir/raw_dir(slug)`, + `utm_projection_for_lonlat`, `lonlat_to_utm_pixel`, `centered_bounds`, `year_range`, + `write_label_geotiff(...)`, `write_sample_json(...)`, `write_dataset_metadata(...)`. + Constants: `RESOLUTION=10`, `CLASS_NODATA=255`, `REGRESSION_NODATA=-99999`, `MAX_TILE=64`. +- `rslearn_read.py` — `iter_windows_metadata(ds_path)` (fast direct read of window + metadata.json), `read_label_vector(...)`, `read_label_raster(...)`. +- `rasterize.py` — `geom_to_pixels(geom, src_proj, dst_proj)`, + `rasterize_shapes(shapes_in_pixel_coords, bounds, fill, dtype, all_touched)`. +- `sampling.py` — `balance_by_class(records, key, per_class, total_cap=25000)` (enforces + the 25k per-dataset cap by default), `bucket_balance_regression(records, value_key, + total, n_buckets)`, `encode_detection_tile(positives, tile_size, positive_size=1, + buffer_size=10, ...)`, constant `MAX_SAMPLES_PER_DATASET=25000`. +- `download.py` — `download_http`, `download_s3_unsigned`, `download_zenodo`, `hf_download` + (all atomic). +- `datasets/{slug}.py` — per-dataset script: a `main()` that produces all outputs and is + runnable/idempotent (skip already-written `{sample_id}.tif`). + `datasets/olmoearth_lcmap_land_use.py` is a complete worked example (sparse points → + `points.geojson` via `io.write_points_table`). + +**Performance — this matters:** weka small-file I/O is ~70 ms/file cold. Reading tens of +thousands of source windows or writing thousands of patches **serially is unacceptably +slow** (30+ min). Always use a `multiprocessing.Pool(64)` (with +`rslearn.utils.mp.star_imap_unordered`) for both the scan and the write phases, as the +lcmap example does (26k windows scanned in ~18 s; 5.6k patches written in ~60 s). + +## 7.

Per-dataset agent workflow (SOP) + +0. **Preconditions.** Check disk (§0: ≥5 TB free on weka, else stop). Record + `in_progress` via `manifest.write_registry_entry(slug, "in_progress")` (writes your + `datasets/{slug}/registry_entry.json`; do NOT touch the central registry). +1. **Read the manifest entry** and, if `have_locally`, inspect the source rslearn dataset + (`config.json`, a few windows, label layer property names). If external, identify the + download mechanism from `source`/`url`. +2. **Triage (accept/reject).** Reject and write only `dataset_summaries/{DATASET}.md` + (with reason) if any of: + - Not accessible: needs an account/credential or interactive auth we don't have + (Kaggle, DrivenData, Earth Engine, registration portals), dead link, or license + forbids use. **FIRST check `.env` for a usable credential before + rejecting** — it holds authorized project credentials the user has approved for this + work: `NASA_EARTHDATA_USERNAME`/`NASA_EARTHDATA_PASSWORD` (NASA URS → ORNL DAAC, OB.DAAC, + LP DAAC, etc.), `COPERNICUS_USERNAME`/`PASSWORD` (Copernicus Data Space), `CDSAPI_KEY` + (Climate Data Store), `M2M_USERNAME`/`M2M_TOKEN` and `TEST_USGS_LANDSAT_*` (USGS + EarthExplorer/M2M), `PL_API_KEY` (Planet), and GEE service-account creds. For NASA + Earthdata, source those two vars and write a `~/.netrc` (`machine urs.earthdata.nasa.gov + login password `, chmod 600) so URS OAuth redirects authenticate. **Do NOT + use credentials found elsewhere** (e.g. other users' `~/.netrc` or tokens under other + home dirs on weka) — only `.env`. If `.env` has no matching + credential and unauthenticated/mirror/alternate access fails, try briefly then **reject + with `notes: "needs-credential: "`** so it collects in the registry for the user to + act on later (provide creds or a pre-downloaded copy). Credentials NOT in `.env` (so + still rejections): NEON API token, ISMN portal login, HuggingFace gated-repo access, + Zenodo restricted-access approvals, and per-dataset registration portals (xView3, etc.). + **Exception — transient source/infra errors** (server HTTP 5xx, timeout, rate-limit, + temporarily-empty GeoServer) on an otherwise-usable, no-credential source: do NOT mark + `rejected`. Record **`temporary_failure`** (see §1a) with the concrete error and retry + steps in `notes`, so it is retried later rather than treated as a permanent drop. + - A **preferred reference alternative is in the manifest** and this is the paired map + product → defer to the reference (note the pairing). + - Phenomenon not observable at 10–30 m from S2/S1/Landsat (individual small trees, + VHR-only wildlife, coordinate-fuzzed points like FIA ~1 mi), and no aggregate/mask + representation salvages it. + - **Pre-2016 labels: reject if ALL labels fall before 2016** (outside the Sentinel era, + with no usable post-2016 window). If the dataset is a **mix** of pre- and post-2016 + labels, keep only the post-2016 subset and process normally (filter the rest out); only + a dataset whose labels are *entirely* pre-2016 is rejected on this ground. Note the + cutoff/filtering in the summary. (Landsat-era-only labels are still rejected under this + rule — we anchor to the Sentinel era.) + - Label semantics can't be expressed as per-pixel classification or regression. + - **No recoverable geocoordinates.** Many "ML-ready" patch/tensor releases (PNG tiles, + `.npy` stacks, anonymized CSVs) strip lon/lat, so labels can't be placed on the S2 + grid — this is a common, fast rejection. **Check georeferencing cheaply first** + (inspect the archive file listing / datasheet / a sample file's CRS) **before** + downloading multi-GB archives. A per-sample tile/region id alone (e.g. an MGRS tile + without within-tile pixel index) is not sufficient. If unrecoverable, reject. + - ~~Change/event label whose change date is not known to within ~1-2 months~~ — **NO + LONGER a rejection reason.** The pre/post two-window scheme (§5) places coarsely-timed + changes (year-resolved, multi-year pre/post comparisons) in the gap between a "before" + and an "after" window, so they are now usable. Process such datasets under §5 (do not + reject on timing). Only reject a change dataset for an independent reason (no + geocoordinates, all pre-2016, not observable at 10-30 m, etc.). + - **Impractical download volume for the label signal.** Only the *labels* are needed — + pretraining supplies its own imagery. If the labels are only distributed inside very + large bulk archives (e.g. whole-region/full-planet OSM extracts, multi-TB SAR scene + sets) and you'd have to pull tens of GB (or many such archives) to extract a thin label + layer, do NOT bulk-download. Try: (a) a lighter label-only/metadata endpoint, (b) a + smaller bounded set of regions/tiles (§5), or (c) range-request/selective extraction of + just the needed files. If none is feasible, **reject** with `notes: "impractical-download: + "` (retain any partial download for a future re-scope) rather than spending hours + pulling data. (openstreetmap_leisure_tourism_extracts was rejected on this ground after a + ~14 GB whole-region OSM download loop produced no labels.) + Otherwise **accept**; classify as classification vs regression. +3. **Download** raw to `raw/{DATASET}/` (or write `SOURCE.txt` for local). Download only what + the labels require; prefer selective/range extraction over pulling whole bulk archives. +4. **Analyze**: enumerate classes / value range, CRS/resolution, per-record time, class + distribution; capture any per-class descriptions from the source (for `metadata.json`); + decide tile size, detection parameters, buckets, time-range rule. +5. **Write the per-dataset script** using shared utils; produce `metadata.json`, + `locations/{SAMPLE_ID}.tif` + `.json`, applying §2–§5. +6. **Verify** (§9). +7. **Write** `dataset_summaries/{DATASET}.md`: source, access method, class/label mapping, + time-range and change handling, tile size, sample counts per class (or regression + stats), rejections/caveats, and the exact command to reproduce. +8. **Record final status** via `manifest.write_registry_entry(slug, "completed", + task_type=..., num_samples=...)` or `(slug, "rejected", notes="...")` — writes your + `datasets/{slug}/registry_entry.json`. Never write the central `registry.json`; the + orchestrator aggregates. + +## 9. Verification + +- Open 3–5 output `.tif`s: confirm single band, correct dtype, UTM CRS at 10 m, size ≤64, + and that pixel values are valid class IDs (or in the regression range) with the declared + nodata. +- Confirm every `.tif` has a matching `.json` with a ≤1-year `time_range` (and + `change_time` set for change datasets), and that `metadata.json` class IDs cover all + values appearing in the tifs. +- Report class-balance counts (≤1000/class) or regression histogram (≤5000 samples). +- **Spatial/temporal sanity check**: for 1–2 samples, load a Sentinel-2 image at the tile's + CRS/bounds/time (via rslearn) and eyeball that the label overlays sensibly (e.g. a + "water" label sits on water). Note any misalignment in the summary. +- Re-running the script must be idempotent (skip existing outputs). + +--- + +## Critical files (for the implementer of the shared module) + +- Manifest: `olmoearth_pretrain/data/open_set_segmentation_datasets.json`. +- New shared code: `olmoearth_pretrain/open_set_segmentation_data/` (§6). +- New summaries: `data/open_set_segmentation_data/dataset_summaries/`. +- This task spec: `data/open_set_segmentation_data/AGENT_SUMMARY.md`. +- Templates to mirror: `dataset_creation/wri_canopy_height_map/download_wri_canopy_height_map.py`, + `dataset_creation/rslearn_to_olmoearth/{cdl.py,eurocrops.py}`, + `rslearn_projects/rslp/seagrass/create_test_windows.py`. + +## Suggested build order + +1.

Annotations come at three +granularities: (1) **binary** waste presence/absence (`is_candidate_location`), (2) +**multi-class multi-label** waste object / storage-mode categories on a subset +(`valid_fine_grain=1`, 715 images; 22 categories across two supercategories +`Type_of_object` and `Storage_mode`), and (3) **weakly-supervised segmentation masks** +around relevant waste objects (COCO-style, in image-pixel space) on a further subset. + +Image sources: **GE** (Google Earth) 6,750, **AGEA** (Italian agricultural aerial +orthophotos) 3,450, **WV3** (WorldView-3) 234 — all delivered as `.png`. Aerial/GE imagery +is ~0.2–0.5 m/px. + +## Triage — checked cheaply, before any bulk download (spec §8.2) + +The image data is ~18 GB (six `imagesN.zip`, ~3 GB each). Per the spec's "check +georeferencing cheaply first" rule, only the two small COCO annotation files were pulled +(`training.json` 2.9 MB, `testing.json` 1.7 MB → `raw/aerialwaste_landfills/`); the image +zips were **not** downloaded. + +Every image record has exactly these keys (verified across all 10,434 records in both +splits): + +``` +file_name, id, categories, img_source, site_type, severity, evidence, +valid_fine_grain, width, height, is_candidate_location +``` + +There is **no** latitude/longitude, CRS, EPSG, geotransform, corner-coordinate, bounding +box, or MGRS/tile field anywhere — at the top level (`info`, `categories`, `images`, +`meta_properties`), in any image record, or referenced by the README schema. `width`/ +`height` are pixel dimensions of the crop only. Images are keyed solely by an integer +`id` (`3456.png`, …). + +## Why rejected — no recoverable geocoordinates (fundamental, spec §8.2 / §2) + +1. **No recoverable geocoordinates (primary).** OlmoEarth pretraining co-locates labels + with Sentinel-2/S1/Landsat imagery by geography + time. AerialWaste's labels (image- + level classes and the COCO pixel masks alike) live in the pixel space of anonymous PNG + crops with no lon/lat and no CRS, so they cannot be projected onto the S2/UTM grid. A + per-image numeric id is not sufficient (spec §8: "A per-sample tile/region id alone … + is not sufficient"). This is the canonical fast "ML-ready PNG tiles strip lon/lat" + rejection. The omission is by design: exact locations of (often illegal) landfills are + deliberately withheld for enforcement/privacy reasons, so no per-image coordinate table + is published on Zenodo, the GitHub repo, or aerialwaste.org. + +2. **Phenomenon not observable at 10–30 m (secondary).** Even with coordinates, the + fine-grained targets — heaps, full containers, big bags, pallets, drums/bins, tyres, + scrap, corrugated (asbestos) sheets, etc. — are sub-metre to a few metres and were + annotated on ~0.2 m aerial imagery; they are not resolvable by Sentinel-2/Landsat at + 10–30 m (spec §8). Only whole large landfill *sites* could conceivably be observable, + which reduces the usable signal to scene-level presence. + +3. **Scene-level patch classification (secondary).** The dominant annotation is binary + waste presence over heterogeneous candidate-site crops (production sites, farms, + degraded/abandoned areas). That is scene/patch classification, not per-pixel + segmentation of a coherent land-cover patch (spec §4 "scene-level"), and would be + rejected on that ground too. + +4. **License caveat.** The GitHub README states **CC-BY-NC-ND** and that Google Imagery + use must follow Google Earth terms; NC-ND forbids derivative redistribution. The Zenodo + record and manifest list plain CC-BY. This discrepancy is a further reason for caution, + but the decisive, permanent blocker is (1). + +Because the primary blocker is permanent (the georeferencing simply is not in the release +and is intentionally withheld), this is `rejected` (fundamental), not `temporary_failure` +or `needs-credential`. No `datasets/` label outputs were written; the only weka artifacts +are the two triage JSONs under `raw/aerialwaste_landfills/` and this dataset's +`registry_entry.json`. + +## If this is ever revisited + +Salvage would require the authors/ARPA to release a per-image **coordinate or footprint +table** (lon/lat centre or UTM bounds + acquisition date per `id`). With that, only the +large-site scene labels could be recast — e.g. as a static-window `waste_site` presence +class over a small ≤64×64 tile — and only for sites genuinely observable at 10–30 m; the +fine waste-object masks would remain unusable at Sentinel resolution.

Each occupied cell → one **64×64 (640 m) tile** in the local **UTM** projection at + **10 m/pixel**, centered on the cell center. Every segment overlapping the cell is + reprojected to UTM pixel space, buffered by ~1 px (`all_touched`) → ~20–30 m (2–3 px) + wide line, and rasterized (value 0), clipped to the tile; non-road = nodata (255). +3. Tiles whose road mask has `< 3` road pixels are dropped (trivial slivers from + bbox-overlap membership). 2,953 of the sampled cells dropped this way. +4. **Sampling:** 94,284 > 25,000 cap, so a deterministic seeded (seed 42) random subsample + of 25,000 cells is taken before rasterization; 22,047 survive the min-pixel filter. +5.

Three product levels are distributed: + +- **L2a Basic** — per-satellite-track line-of-sight (LOS) velocity + displacement time + series at native PS/DS point density (~20×5 m footprint), one value per measurement point. +- **L2b Calibrated** — the same, GNSS-calibrated to an absolute reference (2016–present, + updated yearly; "Calibrated 2016-present (vector)"). +- **L3 Ortho** — LOS velocities decomposed into **vertical (up–down)** and **east–west + horizontal** velocity components, resampled onto a regular **100 m grid** + ("Ortho, 100 m"). This is the gridded-raster form referenced in the manifest. + +Each point/pixel carries a **multi-year average velocity (mm/yr)** plus a full displacement +time series. Negative vertical velocity = subsidence (sinking), positive = uplift, near-zero += stable. This is an excellent, in-scope signal for this pipeline: velocity is a per-pixel +continuous quantity (regression) that is directly derivable, and the 100 m L3 grid is +coarser than the 10 m target but resamples cleanly. + +## Why it is rejected (needs-credential) + +EGMS data is downloadable **only** through the EGMS Explorer web application, which is gated +behind **EU Login** (`ecas.ec.europa.eu`) and an interactively-generated, time-limited +session token: + +1. The download endpoint is + `https://egms.land.copernicus.eu/insar-api/archive/download/{FILE}.zip?id={TOKEN}`. + The `{TOKEN}` is a ~32-character time-limited user-session id **generated only by + authenticating on the EGMS Explorer in a browser** and extracted from the tail of any + download link the Explorer produces (this is exactly how the community `EGMStoolkit` + works — you paste the manually-copied token via `-t`; the toolkit has **no** + username/password login path). There is no documented REST/OAuth token exchange. +2. Tested here: `GET .../insar-api/archive/download/EGMS_L3_..._2018_2022_1.zip` **without a + token returns HTTP 401**. There is no unauthenticated/anonymous download and no open + mirror of the bulk tiles. +3. `egms.land.copernicus.eu` states plainly: *"You are not logged in. You must log in before + performing a search,"* and the only login is the **EU Login** button. + +**The credential in `.env` does not apply.** `.env` holds +`COPERNICUS_USERNAME`/`COPERNICUS_PASSWORD` (favyenb@allenai.org), but these are **Copernicus +Data Space Ecosystem (CDSE)** credentials, a *different* identity system from EU Login. +Verified during triage: those credentials successfully obtained a valid `access_token` from +the CDSE Keycloak endpoint (`identity.dataspace.copernicus.eu/.../CDSE/.../token`), +confirming they are CDSE-realm credentials — **not** EU Login (ECAS) credentials, and not an +EGMS session token. EGMS / Copernicus **Land** (`land.copernicus.eu`) authenticates against +EU Login, for which `.env` has no username/password, and even a valid EU Login would still +require replicating the Explorer's interactive session to mint the time-limited download +token. + +Per SOP §8 this is a **persistent access gate / registration portal we do not have +credentials for**, so it is `rejected` with `notes: "needs-credential: EGMS Copernicus Land +registration"` — **not** `temporary_failure` (the 401 is an intended auth gate, not a +transient outage). No bulk archives were downloaded; only the small auth checks above were +performed. + +## Intended recipe (if a token / EU Login is provided later) + +Chosen framing: **regression on vertical displacement velocity (mm/yr)** from the **L3 Ortho +(100 m)** product, over a **bounded set of representative European regions** (do NOT pull the +whole continent — §5). Rationale for regression over the manifest's suggested +subsidence/uplift/stable classification: velocity is intrinsically continuous, the class +boundaries (e.g. |v| < 2 mm/yr = stable, v ≤ −2 = subsidence, v ≥ +2 = uplift) are arbitrary +thresholds that discard signal, and a regression target preserves magnitude. (If a +classification variant is ever wanted, record the thresholds explicitly in `metadata.json`; +±1.5–2 mm/yr is the commonly-cited stability band.) + +Concrete plan: +- **Regions**: sample tiles from a handful of well-known, high-signal ground-motion areas to + span the value range — e.g. the Netherlands / Po Valley / Venice (strong subsidence), + Groningen gas field, London/Thames, Mexico-City-analogue European basins, plus large + spatially-stable bedrock regions (Scandinavian/Alpine hardrock) for near-zero velocities. + Draw only enough 100 m tiles to reach the target count. +- **Target count**: ≤ **5000** regression samples (well under the 25k cap), optionally + bucket-balanced across the velocity range if the raw distribution is strongly peaked near 0 + (`sampling.bucket_balance_regression`), since most of Europe is stable. +- **GeoTIFF spec (§2)**: crop ≤64×64 windows from the L3 vertical-velocity band, reproject + 100 m → local-UTM **10 m** (bilinear is acceptable for a continuous velocity field; note + it in the summary), single-band **float32**, `nodata = -99999`. + `regression` block: `{"name": "vertical_displacement_velocity", "unit": "mm/yr", + "dtype": "float32", "nodata_value": -99999, "value_range": [observed]}`. +- **Time / change (§5)**: velocities are **multi-year averages**, so treat as a **static + label** with a representative **1-year window** in the Sentinel era (e.g. 2020, within the + product's 2018–2022 / 2019–2023 span), and **`change_time = null`** — ground motion is a + rate, not a dated event, so this is not a change-detection label. +- **Alternative (points)**: if the L2b Calibrated **point** vectors are used instead of the + L3 grid, each PS/DS point is a single-pixel label → use the **point-table GeoJSON** + (`points.geojson`, §2a) with `properties.label = velocity`, again ≤5000 points across the + bounded regions. + +## Reproduce / recover + +No outputs were written to weka `datasets/egms_european_ground_motion_service/` beyond +`registry_entry.json`.

The true tree can lie anywhere within that 1 km cell (up to ~700 m +from the published point). + +For this effort we must co-locate a label with imagery on the 10 m Sentinel-2 grid.

Each file's front is repeated over a few identical features, so + we dedupe with `shapely.ops.unary_union` before rasterizing. + +## Suitability at 10-30 m (accept decision) + +An ice-shelf / glacier calving front is a sharp, physically-real ice/ocean boundary +spanning tens-to-hundreds of km — clearly resolvable in Sentinel-1/-2 and Landsat. The +front line dilated to ~30-50 m (a few px) is meaningful at 10 m/pixel. **ACCEPTED.** +This mirrors the completed `termpicks_greenland_glacier_termini` precedent (Greenland +marine-terminating glacier termini), applied here to Antarctic ice-shelf fronts. + +## Label construction + +- Each front is a per-date **STATE** (a position observed in one image), not a dated + change mask → `change_time = null`. +- Fronts are 100s of km long, far larger than a 640 m tile, so each front is **tiled** + into up to `MAX_WINDOWS_PER_LINE = 4` windows whose centres are sampled (evenly spaced + + jitter) along the line.

This follows the termpicks precedent: for this front-vs-background *binary* +task the background is spatially meaningful (ice interior / open ocean / sea ice), so +explicit ice/ocean-without-front examples are useful, and are analogous to the +detection-style negatives the spec permits. Non-front pixels inside positive tiles are +also real `background` (0), not `nodata`. + +## Why 21,000 tiles rather than ≤1000/class + +The spec's "≤1000 locations per class" classification guideline targets datasets where a +class is a single land-cover/type label. IceLines is instead a **dense multi-temporal +time series of front positions**: the same stretch of coastline is re-observed on many +dates, and each dated front is an independent, temporally-distinct training label (the +front advances/retreats and calves over the record). Collapsing to 1000 tiles would +throw away exactly the inter/intra-annual dynamics that make this dataset valuable, and +would leave `calving_front` as effectively one giant class with almost no samples. The +`termpicks_greenland_glacier_termini` precedent handles this the same way (15,000 +positive + 3,000 negative tiles). We therefore treat each per-date front observation as +its own sample and cap generously **well under the 25,000 hard per-dataset cap**: +18,000 positive + 3,000 negative = **21,000**, drawn from ~5,900 daily fronts across all +51 shelves (≤150 daily files per shelf to balance across shelves and bound download +volume), up to 4 windows per front, then a seeded shuffle to the 18,000 positive budget. + +## Time-range and change handling + +- `change_time = null` (per-date state, not a change event). +- **Tight** time window: `±45 days` (90-day span) centred on the exact observation date. + This is deliberately narrower than the 1-year window termpicks/CaFFe used: Antarctic + fronts advance and calve over the multi-year record, so a tight window keeps the label + aligned with whatever Sentinel-1/-2/Landsat imagery pretraining pairs to it (avoiding + the seasonal-shift misalignment noted as a caveat in those precedents). +- **Post-2016 filter:** the source spans 2014-2023; per spec we keep only observations + from **≥ 2016** (Sentinel era).

Mediterranean coverage bbox (lon 27–36.2, lat 29.2–36.5) — i.e. all over the correct sea area. Both classes are sea-surface phenomena so a full Sentinel-2 overlay render was not performed; coordinate-level validation (exact UTM round-trip within the marine bbox) was used instead. +- Re-running is idempotent (second run: skip 2000). + +## Caveats +- **Large slicks fill the tile.** Oil slicks here are typically larger than a 640 m (64 px) tile — median oil tile is ~93% oil (median 3820 / 4096 px), and 419 of 1000 oil tiles are entirely oil. This is inherent (the 64 px cap is the hard max; many real slicks span several km) and still yields correct "this area is oil" labels. Oil/no-oil contrast comes from the 1000 dedicated look-alike tiles plus the ~455 partial oil tiles. +- **Look-alike localization.** Look-alike patches carry no per-object box, so the whole 640 m center tile is labeled class 1. Justified because the patch was specifically selected for a prominent, spatially-extensive look-alike phenomenon. +- **Bbox (not exact mask) positives.** Oil positives are rasterized bounding-box footprints, so edges are approximate; the 10 px nodata ring mitigates this. + +## Reproduce +``` +python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.oil_slicks_look_alikes_e_mediterranean_sar +``` +Raw label table (re-download if absent, Firefox UA): +``` +curl -A "Mozilla/5.0 (X11; Linux x86_64; rv:128.0) Gecko/20100101 Firefox/128.0" \ + "https://doi.pangaea.de/10.1594/PANGAEA.980773?format=textfile" \ + -o /weka/dfive-default/helios/dataset_creation/open_set_segmentation/raw/oil_slicks_look_alikes_e_mediterranean_sar/pangaea_data.txt +``` diff --git a/data/open_set_segmentation_data/dataset_summaries/oil_spill_detection_dataset_krestenitis_m4d.md b/data/open_set_segmentation_data/dataset_summaries/oil_spill_detection_dataset_krestenitis_m4d.md new file mode 100644 index 000000000..f7edd4847 --- /dev/null +++ b/data/open_set_segmentation_data/dataset_summaries/oil_spill_detection_dataset_krestenitis_m4d.md @@ -0,0 +1,58 @@ +# Oil Spill Detection Dataset (Krestenitis / M4D) — REJECTED + +- **Slug**: `oil_spill_detection_dataset_krestenitis_m4d` +- **Name**: Oil Spill Detection Dataset (Krestenitis / M4D) +- **Source**: M4D-ITI / MDPI — https://m4d.iti.gr/oil-spill-detection-dataset/ +- **Reference**: Krestenitis et al. 2019, "Oil Spill Identification from Satellite + Images Using Deep Neural Networks", *Remote Sensing* 11(15):1762. +- **Family / region**: marine / Global (EMSA CleanSeaNet events, Sep 2015 – Oct 2017) +- **Label type (manifest)**: dense_raster, 5 classes + (oil spill, look-alike, ship, land, sea surface) +- **Status**: **REJECTED** +- **Reason**: No recoverable geocoordinates (coordinate-free JPG/PNG image tiles); + secondary blocker: access gated behind an institutional request/agreement. + +## What the dataset is + +A Sentinel-1 SAR oil-spill segmentation benchmark: ~1000 training + ~110 test images at +10 m nominal spatial resolution, each with an expert-annotated pixel mask over five +semantic classes.

The EMSA/CleanSeaNet coordinates that + drove scene selection are *not* published alongside the chips in any usable per-image + index.

The genus name, lon/lat, split, and a ~1-year time range live +in the window `metadata.json` `options` block (`label`, `lon`, `lat`, `split`); the genus is +also stored as `properties.label` in the window's `label` vector layer (`data.geojson`). The +source additionally ships a rasterized `label_raster` layer and ingested Sentinel-2 imagery, +neither of which is needed here. + +## Task type +Classification — sparse point segmentation.

A coarse bog/fen/palsa scheme is (a) the natural, robust classification target +and (b) keeps all 446 plots contributing — the alternative of using the 39 fine Finnish +types directly would leave most classes with 3–6 samples, which downstream min-count +filtering would drop, erasing the bog/fen signal. The fine type is preserved as an +auxiliary field (below) for anyone who wants a finer label. + +**Auxiliary per-point properties** (in each feature's `properties`): `country`, `site`, +`finnish_peatland_type` (raw 39-value string), `mire_structure` (structural group: +neva/rame/korpi/letto/luhta/palsa), and the cover-fraction quantities named in the +manifest — `pft_sphagnum`, `pft_graminoids`, `pft_woody_stemmed` (shrub), plus +`pft_brown_mosses`, `pft_herbaceous`, `pft_lichen`, `pft_bare_peat`, `pft_water`, and +`tree_basal_area_living` (Σ living pine+spruce+deciduous basal area, tree-cover proxy). +These are regression quantities carried alongside the classification `label` (as +coastbench/gloria do), enabling a cover-fraction regression downstream if desired. + +### Bog/fen mapping caveats + +Finnish sites use the full trophic Finnish peatland classification (Laine et al. 2012), +so their bog/fen assignment is well-grounded. **Estonian sites (123 plots) are typed only +by tree cover** (per the source: `neva`=treeless, `räme`=pine, `korpi`=spruce), with no +explicit trophic status. I mapped Estonian `Rame` (66) and plain `Neva` (27) → **bog** +(the Estonian study sites are dominated by ombrotrophic raised bogs) and +`Neva_luhtainen` (30) → **fen** (flood/riparian influence).

Images come from the GaoFen, SuperView and +BeiJing-2 satellites, 2017–2020, with a 1–3 year span between the two acquisitions. Each +sample has two images (Image1/Image2) and label maps separating newly-built (label1) and +demolished (label2) buildings. It is designed for VHR change-detection benchmarking, not +for pairing with a satellite time series. + +## Why it is rejected + +The open-set-segmentation pipeline pairs each label patch with Sentinel-2 / Sentinel-1 / +Landsat imagery by **geography and time**, so every label must carry real-world +coordinates to reproject to a local-UTM 10 m grid. S2Looking provides none: + +1. **Release format is coordinate-free 8-bit PNG.** The paper states verbatim: "The image + pairs in the dataset are converted from the original TIFF format with 16 bit to PNG + format with 8 bit." PNG carries no CRS and no geotransform. The single distributed + archive (`S2Looking.zip`, ~10.2 GB) lays tiles out under `train|val|test/{Image1, + Image2,label,label1,label2}/` with opaque numeric filenames (e.g. `1.png`); there is no + world file, GeoTIFF, CSV, or coordinate index. +2. **The authors explicitly removed the coordinates.** The dataset was built by cropping + large scenes using "rough coordinate information," but that "geographic coordinate + information has been removed from the data" (removed for the associated challenge and + in the public release). So per-tile lon/lat is not recoverable from the release. +3. **No per-tile coordinate lookup exists.** Region provenance is only "rural areas + throughout the world"; there is no published table mapping the numeric tile IDs to + lat/lon, and the GitHub/Google-Drive/Baidu distributions all mirror the same + coordinate-free PNG archive. + +Because per-tile geocoordinates are unrecoverable, the tiles cannot be resampled to 10 m +and located on the S2 grid — the spec's stated rejection condition (§8.2: no recoverable +geocoordinates). + +### Secondary blockers (moot, but recorded) + +- **Too fine for 10 m.** The labels mark individual rural buildings at 0.5–0.8 m. A single + building footprint is well under one 10 m Sentinel-2 pixel, so the "building appeared / + disappeared" change signal is not resolvable from S2/S1/Landsat; the class set could not + be salvaged by coarsening. +- **No usable change_time.** The pipeline needs a `change_time` to center a ≤1-year window + (§5). S2Looking gives only a dataset-wide 2017–2020 range with a 1–3 year gap between the + two images and **no per-pair acquisition dates**, so a 1-year change window would be + ill-posed even if the tiles were georeferenced. + +## Access method (for the record) + +Public, no credentials strictly required for the data itself (Google Drive + Baidu links, +Baidu password `25Ao`; a ~10.2 GB HyperAI mirror also exists).

Pretraining only uses a + label when an input image window spans that time at that location. Over open water, an S2 + (~5-day revisit) or Landsat 8/9 (~8-day combined) scene that is both within ~1 h of the + cast **and** cloud-free is vanishingly rare — the inspected station was 100% cloudy. The + entire SeaBASS *validation* subsystem exists precisely because coincident in-situ/satellite + ocean-color match-ups are scarce; for a generic (non-ocean-color, non-daily) sensor stack + the realized pairing yield is effectively negligible. The labels would almost never be + usable. +2. **Weak per-pixel observability even when a scene exists.** Chl-a retrieval is the domain of + dedicated ocean-color sensors (SeaWiFS/MODIS/VIIRS/OLCI/PACE) with narrow high-SNR blue + bands (412/443/490 nm) and specialized over-water atmospheric correction. S2/Landsat are + land sensors: fewer/wider bands, low SNR over dark water, coarse aerosol correction over + water, plus sun-glint/adjacency effects. In open-ocean Case-1 waters (the bulk of SeaBASS, + chl ~0.01-1 mg/m^3) the reflectance signal is below what S2/Landsat resolve reliably; + **S1 (SAR) has zero chl sensitivity**. Coastal Case-2 waters (like the 19 mg/m^3 example) + carry more signal and have published S2 chl algorithms, but are a minority, are confounded + by CDOM/turbidity, and still suffer problem (1).

We + do **not** invent a background class (spec §5): non-declared pixels are ignore, and the + assembly step supplies negatives from other datasets. +- Present crop codes are assigned class ids **0..N-1 by descending global pixel frequency**. + Names come from the taxonomy (e.g. 0=Unknown crops, 1=Olives, 2=Wheat, 3=Barley, + 4=Sunflower, 5=Fallow land, 6=Grapes, 7=Almonds, 8=Rice, 9=Temporary grass crops, …). +- **254-class cap:** the taxonomy has 168 codes (< 254), so all fit in `uint8` and **no + truncation** was needed. Only **95** codes actually appear in the sampled patches; the + other 73 taxonomy codes (crops not grown in / not sampled from these regions) are absent + and simply do not get an id. Downstream assembly drops too-small classes. + +## Processing recipe (dense_raster, spec §4) + +The `labels` raster is already UTM 10 m, so we **reuse the source CRS** and cut +**non-overlapping 64×64 windows** on a 5×5 grid over the top-left 320×320 of each patch +(the 46-px remainder is dropped). Windows with < 5 % declared (non-zero) pixels are +discarded.

All post-2016 (Sentinel era). No change labels. + +## Bounded sample & caveat (HF rate limit) + +The full product is 10,013 patches (~260 GB).

The two **bold** scenes are the +post-2016 (Sentinel-era) subset (~122.6k points), consistent with the manifest +`time_range [2018, 2020]`; the 2009/2010/2013/2015 scenes are pre-2016 and would be +dropped under §8's mixed-era rule. + +Note on classes: the manifest lists `["blue wildebeest", "plains zebra"]`, but the +**released** point data is wildebeest-only and carries **no species attribute** (only an +`id`), so the two manifest classes are not separable from this release. The zebra layer is +not in the open data. + +## Observability triage — FAILS (this is the rejection ground) + +The manifest note is explicit: *"VHR-annotated locations; use for habitat/context, not +direct detection at 10-30 m."* Each label marks **one ~2 m animal** (~1.5–3 m² footprint), +one to two orders of magnitude below the 10–30 m ground sampling distance of +Sentinel-2/Sentinel-1/Landsat. Individual animals are unresolvable, so per §4/§8 the only +possible salvage is an **aggregate herd-density / presence mask at 10 m**. I inspected the +released points to test that — and it does not hold up: + +1. **Animals are mostly dispersed at 10 m, not clustered into detectable herds.** Binning + the two post-2016 scenes onto a 10 m grid: + - **2018 (GE1)**: 51,795 animals in 21,405 occupied 10 m pixels → **mean 2.4, median 2** + animals/pixel, **max 26**. Only **12%** of occupied pixels have ≥5 animals and **1.9%** + have ≥10. + - **2020 (WV2)**: 70,822 animals in 46,609 occupied pixels → **mean 1.5, median 1**, + **max 18**. Only **2.6%** of occupied pixels have ≥5 animals and **0.3%** have ≥10. + + Even the densest pixels (≤26 animals × ~1.5–3 m² ≈ 10–25% areal cover by dark bodies + against bright, heterogeneous savanna grass/soil/shadow) do not yield a spectrally + distinct, reliably-detectable "herd" signal at Sentinel-2's radiometry, and such pixels + are a tiny (<2%) minority. A density mask built from this would be dominated by 1–2 + animal pixels that carry no observable signal — a mask of noise, not of an observable + phenomenon. + +2. **Decisive: the labels are instantaneous snapshots of a *mobile* herd, so they cannot + be co-located with pretraining imagery.** Each shapefile is a single VHR acquisition on + one date. Migrating wildebeest move kilometres per day, so the herd's position is valid + only at that exact instant. OlmoEarth pretraining pairs each label with an + **independently-acquired** Sentinel/Landsat scene by geography + a time window; there is + essentially zero chance the paired scene was captured at the same moment, so the animals + would **not** be in the labeled pixels of the pretraining image. Unlike a burn scar, + clear-cut, or filled reservoir, an animal herd leaves **no persistent post-event state** + in the landscape, so §5's "persistent state → recast as presence/state classification" + escape hatch does not apply either. This spatiotemporal mismatch is fatal independent of + the density argument. + +Because the phenomenon is unobservable at 10–30 m **and** no aggregate/mask representation +salvages it (dispersed density + non-persistent, un-co-locatable mobile snapshots), this is +a clean **reject** under §8, matching the manifest's own guidance. + +## Access / disk (for completeness) + +- Access is fully open: `download.download_zenodo("7810487", raw_dir)` fetched the 15 MB + archive with no credential.

Each sample carries `change_time = 2018-01-24`, +retained as the reference date used to build two adjacent six-month windows via +`io.pre_post_time_ranges(change_time, ...)`: `pre_time_range` — the ~6 months (≤183 days) +immediately before `change_time` — and `post_time_range` — the ~6 months (≤183 days) +immediately after. The two windows are adjacent, split exactly at `change_time` (total +span still ~1 year), and `time_range` is set to null. Pretraining pairs a "before" image +stack with an "after" stack and probes on their difference, so it always straddles the +late-Jan-2018 debris period (undisturbed snowpack before → avalanche-debris texture +after). `metadata.json` sets `is_change_dataset: true`. + +**Why change, not static presence:** avalanche debris is snow — visible for weeks after +the event but gone by the following summer.

Task fit would otherwise be excellent: a genuine +per-plot tree-species / forest-condition label in the Sentinel era (manifest time_range +2016–2026), expressible as sparse-point classification (§2a/§4) — hundreds of US tree +species — or as a plot-level forest/nonforest or biomass regression target. + +## Why it is rejected + +The public FIA release **does not publish placeable geocoordinates.** To protect +landowner privacy (required by the Food Security Act of 1985 / 7 U.S.C. 2276), FIA +deliberately degrades the public LAT/LON in the PLOT table by two mechanisms, both still +in force for the current DataMart release (verified July 2026): + +- **Fuzzing:** most plot coordinates are randomly relocated within **0.5 mile** of the + true location, with the remainder moved **up to 1 mile** — i.e. the true plot is masked + within roughly a 500-acre area. +- **Swapping:** for up to **20% of privately-owned forested plots per county**, the + coordinates are exchanged with a *different similar plot in the same county*, so the + published point may not even be near the plot it describes. + +Actual (unfuzzed) plot coordinates are confidential and shared only rarely under a +specific, limited USFS Spatial Data Services agreement — not available through any +unauthenticated/public path. + +For this effort a label must be co-located with imagery on the 10 m Sentinel-2 grid. A +positional error of up to ~1 mile (~1600 m ≈ **160 pixels** at 10 m) is more than 2× the +maximum 64×64 tile footprint (640 m), so a plot's species/condition label cannot be pinned +to any specific 10 m pixel or even reliably placed within a single tile. Swapped plots can +be arbitrarily wrong. This is exactly the situation the spec names as a rejection: "phenomenon +not observable … coordinate-fuzzed points like FIA ~1 mi, and no aggregate/mask +representation salvages it" (§8) → **no recoverable geocoordinates** (§1a fundamental reason). + +## Judgment calls + +- **Considered a salvageable plot-level aggregate** (per task note: forest/nonforest or + biomass at coarse cells). Rejected: to be robust to ~1 mile fuzzing + county-scale + swapping, an aggregation cell would have to be several km across — far larger than the + 64×64 (640 m) tile cap and the 10 m point grid this effort targets. There is no coarse + representation that both respects the output contract and survives the positional noise. +- **Better georeferenced alternatives already exist in the manifest** for the salvageable + aggregates: `annual_nlcd_reference_data` (NLCD land cover incl. forest classes) and + derived canopy-height / biomass map products cover forest cover/structure with true + georeferencing, so the fuzzed FIA aggregate adds nothing. +- **`rejected`, not `temporary_failure` or `needs-credential`.** The source is fully + accessible without credentials; the blocker is a *permanent, deliberate property of the + public release* (legally mandated coordinate degradation), not a transient outage or a + simple access gate.

Natural non-rock surface types `Water` (id 6) and `Ice` (id 30) are retained + as legitimate, 10–30 m-observable surface units (same treatment as the GLiM sibling). +- Well under the 254-class uint8 cap; no frequency truncation needed. + +**Geologic age** (also in the geodatabase, via the `Age` table) is **not encoded**: a +single-band per-pixel label can hold only one attribute, and surface lithology is the more +directly observable-at-10–30 m property. Age is left for a possible future age-labeled +variant. + +## Processing recipe (mirrors `glim_global_lithological_map.py`) + +SGMC is a generalized ~1:500,000-scale compilation, so — per spec §5 (large derived product) +— we **sample bounded homogeneous tiles from large polygons** rather than tracing boundaries: + +1.

Conversely, one land cover (e.g. temperate forest) appears + under every category. There is no per-pixel imagery signal that maps to IUCN category, + so it is not a learnable per-pixel class. + - **Designation type** (national park vs Ramsar site vs wildlife sanctuary …) is purely + legal/jurisdictional — even less observable than IUCN category. + - **Marine/terrestrial** *is* observable, but it is trivial land/water masking already + covered far better by dedicated products (JRC surface water, land-cover datasets). It + needs nothing from WDPA — and a marine-protected-area boundary sits in open water with + no visible edge at all — so it is not a reason to keep WDPA. + +3. **Polygons are heterogeneous internally.** A single protected area (often + 10²–10⁴ km²) contains forest + water + rock + grassland + settlements. Assigning the + whole polygon one class id gives a per-tile label that disagrees with most pixels in the + tile — the same "too coarse / not per-pixel truth" failure recorded for aggregated-unit + datasets (cf. `optis_operational_tillage_information_system`, `eyes_on_the_ground_kenya`). + +### Why the "defensible target" path was considered and declined + +The task prompt explicitly allowed acceptance *if* a defensible target existed (e.g. "IUCN +category as a weak areal class over genuinely distinguishable protected land").

Stage-of-development (SOD, ice type) and form/floe (FLOE) are ALSO encoded in the +polygon codes and could be produced later as a classification companion (they need +partial-concentration weighting), but SIC is the recommended primary target and the one we +build here. See the summary for the choice rationale. + +We use ONLY the ice-chart label (``polygon_icechart`` + ``polygon_codes``) + the SAR +geolocation grid (``sar_grid_line/sample/latitude/longitude``) from each NetCDF. We do NOT +use the SAR or AMSR2 imagery -- pretraining supplies its own imagery. The full archive is +huge (~333 GB), so we do NOT bulk-download. NetCDF4 is HDF5, and the ice-chart variable is +gzip-compressed to ~30 KB, so we use **HTTP Range requests** (``download.HttpRangeFile`` + +h5py) to selectively read ONLY those few variables from each remote file -- ~60 KB per scene +instead of ~500 MB (spec 5/8 selective extraction). The extracted arrays are cached to a +small per-scene ``.npz`` in ``raw/{slug}/`` so re-runs are offline + idempotent. We sample a +bounded, seasonally- and regionally-stratified set of scenes (``N_SCENES``). + +Concentration mapping (SIGRID-3 ``CT`` -> percent). ``polygon_icechart`` is a raster of +polygon ids; ``polygon_codes`` is the per-polygon SIGRID-3 attribute table +(``id;CT;CA;SA;FA;CB;SB;FB;CC;SC;FC;CN;CD;CF;POLY_TYPE``). We read the TOTAL concentration +``CT`` of each polygon: + + CT 00/01/02 (ice-free / <1/10 / bergy water) -> 0 % + CT 10..90 (k/10) -> k*10 % + CT 91 (9+/10 .. <10/10) -> 95 % + CT 92 (10/10, incl. fast/compact ice) -> 100 % + CT "ab" range codes (a<=b, e.g. 46=4..6/10) -> midpoint*10 % + CT 99 / negative / undetermined -> nodata + +Resolution / label-generalization CAVEAT. Ice charts are drawn MANUALLY by ice analysts as +generalized polygons over large areas; the effective native resolution is coarse (many km, +not the SAR pixel), so a "10 m" label here is an UPSAMPLED coarse polygon field, not a fine +per-pixel measurement. We warp with **nearest** resampling (categorical polygon field) and +tile to 10 m only to meet the common output spec; the true information content is coarse. +This is documented in ``metadata.json`` and the summary. + +Georeferencing. The ice chart is in SAR *swath* geometry (not a regular CRS grid). Each +NetCDF carries a coarse line/sample -> lon/lat geolocation grid. We build GCPs from that grid +and warp the concentration raster to a scene-local UTM projection at 10 m/pixel (UTM zone +from the scene-mean lon/lat), nearest resampling. We then tile the warped raster into 64x64 +patches. + +Time range. A sea-ice chart is valid only around its SAR acquisition, and ice is DYNAMIC, so +we treat it as state-at-time (spec 5): ``change_time=null`` with a TIGHT +/-3-day window +(6 days total) centered on the acquisition timestamp parsed from the filename (e.g. +``20190519T194908``). This is well under the 360-day pretraining cap and short enough that +the regional concentration field is roughly stable while still giving S1/S2 (very frequent +at Arctic latitudes) a chance to pair. All scenes are 2018-2019 (post-2016). + +Sampling: regression, up to ``TOTAL`` (5000) tiles, **fixed-bucket balanced across the mean +concentration** (the SIC distribution is strongly bimodal: lots of open water 0 % and lots of +compact pack ice 100 %, fewer intermediate) so the corpus spans the full concentration range. +Tiles that are >50 % nodata are dropped. + +Run: python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.ai4arctic_asip_sea_ice_dataset +""" + +import argparse +import multiprocessing +import random +import re +import time as _time +import urllib.request +from collections import Counter, defaultdict +from datetime import UTC, datetime +from typing import Any + +import numpy as np +from affine import Affine +from rasterio.control import GroundControlPoint as GCP +from rasterio.crs import CRS +from rasterio.warp import Resampling, reproject +from rasterio.warp import transform as warp_transform +from rslearn.utils.geometry import Projection +from rslearn.utils.mp import star_imap_unordered + +from olmoearth_pretrain.open_set_segmentation_data import download, io, manifest + +SLUG = "ai4arctic_asip_sea_ice_dataset" +NAME = "AI4Arctic / ASIP Sea Ice Dataset" + +FIGSHARE_ARTICLE = "13011134" +FIGSHARE_API = f"https://api.figshare.com/v2/articles/{FIGSHARE_ARTICLE}" + +# Bounded scene sample: seasonally (12 months) x regionally stratified, preferring the +# smallest file per (month, region) cell to cap the download volume. ~3 scenes/month. +N_SCENES = 36 +PER_MONTH = 3 + +TILE = 64 +TOTAL = 5000 # regression per-dataset target (<= 25k cap) +CAND_PER_SCENE = 6000 # cap candidate tiles kept per scene (bounds memory; >> needed) +MAX_NODATA_FRAC = 0.5 # drop tiles that are more than half nodata +HALF_WINDOW_DAYS = 3 # tight +/-3-day window around the acquisition (dynamic ice) +SEED = 42 + +# Fixed mean-concentration bucket edges (percent).

The physical field boundaries (bunds/dikes/paths) are + typically 1-5 m wide -- sub-pixel at Sentinel-2's 10 m GSD and not separable as their own + spectral class; a dilated 1-px boundary would consume most of these small fields, leaving + no interior. The field *extent* IS observable at 10 m, so we encode field vs background. + Because AI4SmallFarms exhaustively digitized every field inside each 5x5 km tile, the + non-field (0) pixels are a genuine negative (not undeclared fields), unlike AI4Boundaries. + +Processing (task spec §4 polygons, §5 balancing): + * Per group (5x5 km tile): pick the local UTM (48N for centroid lon<108, else 49N), + reproject polygons into that UTM's 10 m pixel grid, and tile the group extent into + non-overlapping <=64x64 windows (spec cap 64).

Sentinel-2 pre/post- +fire acquisitions over California wildfires with **binary burned-area masks** derived from +CAL FIRE (California Dept. of Forestry and Fire Protection) fire perimeters, mapped onto +the imagery. + +We use the pre-patched file `raw/patched/512x512.hdf5`: 534 patches of 512x512 px at +**20 m/pixel** (Sentinel-2 20 m grid), each keyed `{uuid}_{patch}` and holding `post_fire` +(12-band uint16), optional `pre_fire`, and a binary `mask` (uint16 {0,1}; 1 = burned). Only +patches containing >=1 burned pixel are present in this file. Per-patch georeferencing (CRS ++ x/y pixel-center coordinate arrays + post-fire acquisition timestamp) comes from the +companion `metadata.parquet` (keyed on uuid+patch, `post==True` rows). + +Class scheme (dense per-pixel CLASSIFICATION, matching the manifest's 2 classes): + id 0 = unburned (mask == 0, observed) + id 1 = burned (mask == 1) + 255 = nodata/ignore (all-12-band-zero fill at S2 tile edges, ~14% of patches) + +Processing (label_type = dense_raster): each 512x512 20 m patch is already in local UTM. +We cut it into 32x32 (20 m) blocks and **upsample each block 2x with nearest resampling** +to a 64x64 tile at 10 m (categorical label -> nearest, never bilinear), georeferenced from +the block's UTM coordinates. Sampling is **tiles-per-class balanced** (spec 5): a tile +counts toward every class present in it (>= MIN_CLASS_PX px), rarer class (burned) filled +first, up to PER_CLASS tiles/class. + +Time range: the burn is a change/event label. `change_time` is set to the post-fire +Sentinel-2 acquisition timestamp (a post-event date - the fire occurred shortly before it, +between the pre- and post-fire acquisitions). We emit two independent six-month windows via +`io.pre_post_time_ranges(change_time, pre_offset_days=90)`: `post_time_range` starts at +`change_time` and runs ~6 months (<=183 days) forward, and `pre_time_range` ends 90 days +before `change_time` (a guard offset, since the fire precedes the acquisition) and spans +~6 months (<=183 days) backward from there, keeping the pre window entirely before the +fire. `time_range` is null.

We set the per-sample ``change_time`` +to the fire's ALARM_DATE (kept as the reference for building the windows) and, instead of +a single centered window, emit two adjacent six-month windows split at ``change_time``: +``pre_time_range`` (the <=183 days immediately before) and ``post_time_range`` (the <=183 +days immediately after), with ``time_range`` set to null. The windows are built via +``io.pre_post_time_ranges(change_time, ...)``, so pretraining pairs a "before" image stack +with an "after" stack spanning the fire (before + after the scar appears) and probes on +their difference. Only fires with YEAR_ >= 2016 (Sentinel era) are used; FRAP's pre-2016 +perimeters are filtered out. + +Tiling: perimeters are reprojected to a local UTM projection at 10 m/pixel. A fire whose +footprint fits in a 64x64 tile (640 m) yields one centered tile; larger fires are gridded +into non-overlapping 64x64 windows, keeping windows that actually intersect the perimeter, +and randomly sampling up to MAX_TILES_PER_FIRE of them for geographic spread.

NBAC fires carry +day-resolved fire dates, so we set the per-sample ``change_time`` to the fire's start +date -- ``HS_SDATE`` (satellite hotspot start) preferred, else ``AG_SDATE`` (agency +start), else ``CAPDATE`` (same-year mapping capture) -- and keep it as the reference for +building the windows. Instead of a single centered window, we emit two adjacent six-month +windows split at ``change_time``: ``pre_time_range`` (the <=183 days immediately before) +and ``post_time_range`` (the <=183 days immediately after), with ``time_range`` set to +null. The windows are built via ``io.pre_post_time_ranges(change_time, ...)``, so +pretraining pairs a "before" image stack with an "after" stack spanning the fire (before + +after the scar appears) and probes on their difference. This meets the hard +timing-precision rule (event known to <= ~1-2 months): HS/AG start dates are exact fire +dates; the small CAPDATE fallback (~1% of fires) is a same-fire-year capture of the +scar.

Distributed as cloud-optimized "tortilla" files on the HuggingFace repo +``tacofoundation/cloudsen12`` and read lazily with the legacy ``tacoreader`` client +(``pip install 'tacoreader<1.0'``); mirrors on Zenodo (record 7034410) and ScienceDataBank. + +We use only the **high-quality manual** label tier (``label_type == "high"``) at the +standard **509x509, 10 m** patch size (``real_proj_shape == 509``): 10,000 patches spread +across all continents except Antarctica, each a single Sentinel-2 L1C acquisition +(acquisition dates span 2018-2020, all Sentinel era) already stored in its native local +UTM zone at 10 m/pixel (padded to 512x512; the extra 3 rows/cols on the bottom/right are +0-fill and are never read). + +**Download strategy (robust to HF rate limits).** The tortilla index is built once with +tacoreader and cached to ``raw/{slug}/index.parquet``; thereafter it is reconstructed from +that parquet with no HuggingFace request (the HF index build is heavy and the first thing +anonymous rate-limiting kills). For each patch we then issue a SINGLE HTTP byte-range GET +for its tortilla blob, parse the nested footer locally, slice out the tiny single-band +"target" label GeoTIFF, and discard the S2 imagery bytes (pretraining supplies imagery). +This keeps us to ~1 HF request/patch (vs tacoreader's multi-request vsicurl path) and is +trivially resumable via a per-patch ``.npy`` cache. Because CloudSEN12 is large, we +download only a bounded, class-diverse subset of patches (``--max-patches``, default 2500), +prioritizing the rarest class (thin cloud) so every class reaches its target (spec 5). + +IMPORTANT indexing note: ``tacoreader.load`` sorts rows by ``tortilla:id`` but leaves the +pandas index labels randomized (they differ per load), while ``TortillaDataFrame.read(i)`` +is positional. We therefore never rely on ``.read(idx)`` across processes; workers fetch +labels purely from the per-patch (url, blob_offset, blob_length) parsed from the index. +Every read is validated to contain only class ids {0,1,2,3} (the scribble tier's 0..6 +scheme / 99 fill would indicate a wrong read and is rejected). + +Label semantics (CloudSEN12 4-class manual scheme, Table 2 of the Data-in-Brief paper): + 0 = clear, 1 = thick cloud, 2 = thin cloud, 3 = cloud shadow. +These map directly to output class ids 0..3 (uint8). Every pixel in a "high" patch is +labeled, so no nodata occurs in practice; nodata sentinel 255 is still declared for the +open-set contract. + +Recipe (spec 4 dense_raster, spec 5 tiles-per-class balanced): each 509x509 label is tiled +into 64x64 patches on an 8x8 grid that evenly covers the valid extent. A tile counts toward +every class present in it; tiles are selected rarest-class-first up to 1000 tiles/class, +25k total.

Ten data records span five imagery +sources over U.S. Pacific/Gulf/Atlantic/Great-Lakes coasts. Labels were produced +with the Doodler human-in-the-loop tool. + +Each record is a ``{source}_{nclasses}_{version}.zip`` of NPZ files, one NPZ per +labeled image. An NPZ holds ``label`` (one-hot HxWxC uint8, channel k == class k +of ``classes``), ``classes`` (the class-name list), the RGB ``image``, etc. +Georeferencing lives in the release-wide ``CoastTrain_imagery_details.csv``: +per-image easting/northing footprint (XMin/XMax/YMin/YMax), ``epsg`` (a +projected UTM CRS), acquisition date, and pixel size. The doodled raster is a +resampled version of the native scene, so the CSV footprint (acc_georef ~8 m) is +the authoritative extent; we build the source affine from it. + +Records processed (label_type = dense_raster, satellite + aerial at/near 10-30 m): + * Sentinel2_11, Sentinel2_4 (native 10 m) - best fit + * Landsat8_11, Landsat8_12 (native ~15-30 m) + * NAIP_11, NAIP_6 (1 m aerial, resampled to 10 m; coarse coastal + land-cover survives, fine urban detail does not) +Records SKIPPED and why: + * Orthophoto_8/9/12 (UAS orthomosaics ~0.05 m): footprints are only ~50-100 m + (5-10 px at 10 m) and the fine coral/sediment/anthropogenic zonation they + capture is unresolvable at 10 m -> not useful as 10 m tiles. + * Quadrangles_7 (USGS aerial ~6.8 m): ALL images are 2008/2012 (pre-Sentinel + era) -> excluded by the >=2016 filter anyway. +Per-image time filter: only acquisition year >= 2016 is kept (Sentinel era); +pre-2016 NAIP/Landsat scenes are dropped. + +Unified class scheme (dense per-pixel CLASSIFICATION).

Road development in Congo Basin forests is monitored +from 2019 onward by applying a deep-learning model to 10 m Sentinel-1 + Sentinel-2 +imagery, producing automated monthly road detections.

Single foreground class: + 0 = forest road (a mapped forest-road segment; dilated to ~20-30 m so it registers + at 10 m). +This is a **positive-only** dataset (spec S5): non-road pixels are left as +nodata/ignore (255) -- we do NOT fabricate a background class or negative tiles; the +assembly step supplies negatives from other datasets. + +Suitability at 10 m: the source product is *itself* derived from 10 m S1/S2 imagery +with a deep-learning detector, i.e. these roads are exactly the linear disturbance +features resolvable at 10 m in Sentinel imagery (logging / selective-logging access, +a forest-degradation proxy). A centerline dilated to ~2-3 px is a meaningful 10 m +label. ACCEPTED. + +Presence vs change (spec S5): each segment carries an OPENING month/year, which could +support a change-label framing. But a road is a **persistent** feature once built, so +(per the task instruction and spec S5's persistent-post-change-state clause) we treat +this as a presence/state segmentation with ``change_time=null`` and a static 1-year +window. The window is anchored on the **latest** opening year among the segments in a +tile, so imagery in that year is guaranteed to post-date construction of every road in +the mask (roads opened earlier persist). All anchor years fall in the manifest range +[2019, 2024]. + +Tiling: the road network is partitioned onto a fixed 640 m grid in the source +(Mollweide) CRS; each occupied cell becomes one 64x64 (640 m) UTM 10 m tile centered on +the cell center, into which every road segment overlapping the cell is rasterized +(clipped to the tile). 94,284 cells are occupied; we sample MAX_SAMPLES (25,000) cells +(deterministic seeded subsample) to honor the 25k per-dataset cap.

We use the +**Level 2** product: L2 features are the annual maximum RTS extent per calendar year +(L1 per-image footprints dissolved on the ``year`` attribute). 77,405 L2 polygons span +years 2018-2023 across circum-arctic hotspots (NW Canada, Siberia, ...), EPSG:4326. + +Task: **positive-only single-class polygon segmentation** (label_type: polygons). + + 0 = retrogressive thaw slump / active-layer detachment slide + 255 = nodata / ignore (everything outside a slump footprint) + +Only ONE foreground class is expressible: the DARTS release carries no per-feature RTS-vs- +ALD attribute (the model detects RTS + ALD as a single "active slumping" target class), +so the manifest's two classes are represented by one unified class. Per spec section 5 this +is a positive-only / no-background dataset: we do NOT fabricate synthetic negatives; non- +polygon pixels are left 255 (assembly supplies negatives from other datasets). + +Annually-resolved handling (spec section 5): each L2 feature is a footprint for one calendar +``year``. A thaw-slump scar is a *persistent* geomorphic feature (it stays visible long +after any single year's retreat), and the annual resolution here is coarser than the +~1-2 month change-timing bar for change labels. So this is treated as **presence/state +classification**: change_time = null, time_range = the static 1-year window anchored on the +feature's observation year (NOT a change label). A slump observed in multiple years yields +one separate annually-resolved sample per year -- that is the intended annual resolution. + +Rasterization: each selected feature -> one 64x64 UTM 10 m tile centered on the polygon +(centroid, or an interior representative point for concave shapes). All L2 polygons **of +the same year** intersecting the tile bbox are burned to class 0 (all_touched=True so tiny +slumps -- median ~2188 m^2, ~22 px -- survive); the rest of the tile is 255. Same-year only, +so the mask stays temporally consistent with the tile's 1-year window. Polygons are read on +demand from the GeoPackage with a pyogrio bbox filter (GPKG R-tree spatial index), so both +scan and write phases parallelize over a Pool with no giant geometry tree in worker memory. + +Sampling: 77,405 L2 features > the 25,000 per-dataset hard cap, so we take a geographically +stratified round-robin over 1-degree lon/lat cells (as in the sibling mining-polygons +script) to keep dense hotspots from dominating; one tile per selected feature, capped at +25,000 tiles.

Freiburg / Wageningen; Mosig, Schiefer, Kattenborn et al., +Remote Sensing of Environment 2025, doi:10.1016/j.rse.2025.115027). An open-access global +database of centimeter-scale drone/aerial orthophotos with expert-delineated *standing +deadwood* polygons. Each manual label set is tied to one orthophoto and to an +Area-Of-Interest (AOI) multipolygon: inside the AOI, area not delineated as deadwood is +known to be alive tree / non-tree, so the AOI defines the *observed* extent (outside the +AOI is unobserved). Data are public/CC BY and are read from the platform's authentication- +free self-hosted Supabase REST API (https://supabase.deadtrees.earth/rest/v1), the same +public endpoint the website uses. We download ONLY the labels (deadwood polygons + AOI + +per-orthophoto acquisition date); the cm-scale RGB orthomosaics themselves are NOT needed +because pretraining supplies its own Sentinel imagery. + +RESOLUTION / OBSERVABILITY DECISION (the crux for this dataset) +-------------------------------------------------------------- +Native labels are centimeter-scale; an *individual* standing-dead tree is sub-pixel at 10 m +Sentinel resolution. Encoding presence/absence of individual dead trees at 10 m would be +dishonest. Instead we aggregate the cm-scale deadwood mask into the honest 10 m signal that +the manifest itself calls out ("Deadwood fractional cover predictable at 10 m") and that +deadtrees.earth's own satellite models regress: **fractional standing-deadwood cover per +10 m pixel** = (deadwood area) / (observed area) within each 10 m cell, restricted to the +labeled AOI. This is a REGRESSION target in [0, 1]. Aggregation: rasterize the WGS84 +deadwood polygons and the AOI multipolygon onto a fine 0.5 m sub-grid in local UTM, clip +deadwood to the AOI, then average each 20x20 sub-block down to one 10 m pixel. A 10 m pixel +is kept only if >= 50% of its area lies inside the AOI (else nodata); its value is the +fraction of that observed area covered by deadwood. + +Only the manual **expert** delineations (label_source = visual_interpretation) are used -- +the ~12k SegFormer auto-prediction label sets on the platform are a derived ML product and +are excluded to keep this a high-confidence reference bank (SOP: prefer reference over +derived maps). Datasets are further restricted to public, CC BY, non-archived records with +a complete acquisition date in the Sentinel era (>= 2016). AOIs are small drone footprints +(median ~230 m), so most datasets yield a single tile sized to their footprint; larger +airborne AOIs are tiled into a <=64x64 grid. + +Output: single-band float32 GeoTIFFs, local UTM, 10 m/pixel, <=64x64, values = deadwood +fraction 0..1, nodata -99999 (io.REGRESSION_NODATA). change_time=null (single-date state); +one <=1-year time range per tile anchored on the orthophoto acquisition year. + +Run: python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.deadtrees_earth_standing_deadwood +Idempotent: existing raw label files and output .tif tiles are skipped. +""" + +import argparse +import json +import math +import multiprocessing +import urllib.parse +import urllib.request +from typing import Any + +import numpy as np +import tqdm +from rslearn.const import WGS84_PROJECTION +from rslearn.utils.geometry import STGeometry +from rslearn.utils.get_utm_ups_crs import get_utm_ups_projection +from rslearn.utils.mp import star_imap_unordered +from shapely.geometry import shape + +from olmoearth_pretrain.open_set_segmentation_data import io, manifest +from olmoearth_pretrain.open_set_segmentation_data.rasterize import ( + geom_to_pixels, + rasterize_shapes, +) + +SLUG = "deadtrees_earth_standing_deadwood" +NAME = "deadtrees.earth (standing deadwood)" +URL = "https://deadtrees.earth" +DOI = "https://doi.org/10.1016/j.rse.2025.115027" + +SUPABASE = "https://supabase.deadtrees.earth/rest/v1" +ANON_KEY = ( + "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.ewogICJyb2xlIjogImFub24iLAogICJpc3MiOiAic3Vw" + "YWJhc2UiLAogICJpYXQiOiAxNzQwODcwMDAwLAogICJleHAiOiAxODk4NjM2NDAwCn0." + "A3HdTofLNcrRrtDDbDAP9kRBobxXqnUKB6IYHvM6da4" +) +HDR = {"apikey": ANON_KEY, "Authorization": f"Bearer {ANON_KEY}"} + +SUB = 20 # 0.5 m sub-pixels per 10 m cell (10 / 20) +TILE = 64 # hard cap tile size (px) => 640 m +MIN_OBS_PIXELS = 25 # keep a tile only if >= 25 observed (in-AOI) 10 m pixels (0.25 ha) +MIN_CELL_OBS_FRAC = ( + 0.5 # a 10 m pixel is "observed" if >=50% of its area is inside the AOI +) +REGRESSION_TOTAL = 5000 # regression cap per spec (well above expected count here) +MIN_YEAR = 2016 +SEED = 42 + + +# --------------------------------------------------------------------------- +# Supabase REST (authentication-free public read; same endpoint the site uses) +# --------------------------------------------------------------------------- +def _rest_all( + path: str, params: dict[str, str], page: int = 1000, order: str = "id" +) -> list[dict[str, Any]]: + # PostgREST range-paging is only stable with an explicit ORDER BY; without it + # multi-page queries silently skip/repeat rows (observed dropping ~25% of the + # dataset view).

The EID is the +definitive catalog of confirmed terrestrial impact structures (190 confirmed as of the +2018 web release).

License: "free scholarly use" (not-for-profit scientific +resource); attribution to PASSC/UNB recorded below. This research use is in scope. + +There is no bulk download; the catalog is scraped from the HTML.

We FILTER to structures + with a diameter >= 3 km (149 of the 197 parseable structures). The 3 km cutoff is + derived from the encoding + coordinate precision (see below), and every retained + structure is many hundreds of pixels across at 10 m -- clearly a resolvable circular + landform (rim, central uplift, annular structure). Smaller structures (< 3 km) are + dropped: either near the resolution limit or so small that the label tile cannot be + guaranteed to land inside the structure given the catalog's arc-minute coordinates. + * Coordinate precision: EID coordinates are given to the arc-minute (a few to the + arc-second, e.g. Dhala). Worst-case rounding error is +/- 0.5' latitude ~= 0.93 km. + For a 64 px (640 m) label tile centered on the catalog point, the farthest tile pixel + is 0.93 km (coord error) + 0.45 km (tile half-diagonal, 320 m * sqrt(2)) = 1.38 km + from the true structure center. Requiring that <= structure radius gives diameter >= + 2.77 km, rounded up to a clean 3 km cutoff -- so the whole 640 m footprint tile is + guaranteed to lie within the impact structure despite coordinate imprecision. + * Encoding (spec 4, polygons/footprint): impact structures are (roughly) circular and + have a real footprint, so this is NOT a 1x1 point. Each structure is rasterized as a + circular footprint of radius = diameter/2 into a 64x64 UTM tile at 10 m centered on + the structure. Interior pixels = class 0 (impact_structure); pixels outside the + circle within the tile = nodata/ignore (255). Because all retained structures are + >= 3 km across (>= 300 px), the circle covers the entire 640 m tile: each output tile + is a coherent 640 m patch of confirmed impact-structure surface. POSITIVE-ONLY, no + fabricated background class -- the assembly step supplies negatives from other + datasets (spec 5). + * Time validity: impact structures are persistent landforms (ages Ma to Ga). The + formation event is NOT an observable Sentinel-era change, so this is not a change + dataset: change_time=null and a representative recent 1-year window in the Sentinel + era (2020).

A global, wall-to-wall +canopy *top* height map for the year 2020 at 10 m ground sampling distance, produced by a +probabilistic deep-learning ensemble that fuses NASA GEDI spaceborne lidar (RH98 canopy +height reference) with Sentinel-2 optical imagery, with a companion per-pixel predictive +standard-deviation (uncertainty) layer.

Each canopy-height +("_Map") tile is EPSG:4326, ~10 m (1/12000 deg), single-band **uint8** giving canopy top +height in **metres**, with **255 = no-data** (ocean, permanent snow/ice, and pixels the +model masks out). The tile browser (langnico.github.io/globalcanopyheight/assets/ +tile_index.html) enumerates 2651 land tiles; each tile's download URL follows a fixed +template on the libdrive share. + +This is a *regression* dataset (continuous per-pixel canopy top height in metres) and the +map is already 10 m, so it is a `dense_raster`. As a **global derived product** we do +BOUNDED-tile sampling (spec 5): we download a curated, cross-biome set of 35 tiles spanning +tropical/temperate/boreal forest, savanna/woodland, Mediterranean/shrubland, grassland/ +steppe and tundra (see REGIONS), and draw up to 5000 64x64 windows from them. The raw +distribution of canopy height is heavily zero-inflated (deserts, grassland, water edges), +and tall canopy (>30 m) is globally rare (~5% of land), so we **bucket-balance across fixed +height buckets** to get an even spread from 0 m to the tallest canopies instead of a mostly +low/zero-height corpus. We deliberately do NOT filter by the uncertainty (SD) layer: model +uncertainty is strongly correlated with canopy height, so an SD threshold would +preferentially discard the tall-canopy windows we most want to represent. + +Output: single-band **float32** GeoTIFFs, local UTM, 10 m/pixel, 64x64 (~640 m), nodata +**-99999** (io.REGRESSION_NODATA). The uint8 source is converted to float32 metres and the +source no-data value 255 is mapped to -99999 (keeping the standard regression sentinel +rather than the uint8-only 255).

It provides +706,683 agricultural parcels from **Estonia, Latvia and Portugal** for the year **2021**, +each labeled with a harmonized **HCAT** (Hierarchical Crop and Agriculture Taxonomy) +10-digit code and pre-processed into a per-parcel ``.npz`` (Sentinel-2 median time series ++ metadata). Licensed CC-BY-4.0. + +This is the ML-ready **points** product (registry ``label_type: points``); the sibling +``eurocrops`` dataset already covers the full parcel-polygon → dense-raster product, so to +avoid duplication we emit EuroCropsML as the **sparse-point** product per spec 2a/4: +each parcel is one WGS84 point at its precomputed centroid, carrying its crop class. + +Why points (not rasterized polygons): EuroCropsML distributes only per-parcel median time +series + a centroid ``[lon, lat]`` (in each ``.npz``'s ``center`` array) — the parcel +polygons live in the much larger ``raw_data.zip``.

The per-pixel label is a BINARY mining footprint +mask (paper 3.4: "classify each pixel as either mine or non-mine"); the mine-type categories +in the manifest (metallic/coal/non-metallic/quarry) are SITE-level metadata, not per-pixel +classes, and no site->type table ships in the archive, so we use the honest binary scheme: + id 0 = background (non-mine), id 1 = mining footprint. + +Georeferencing (spec 8): the label tifs are written WITHOUT a CRS/geotransform (identity), +but each shares the exact pixel grid of its sibling image tif, which IS georeferenced +(EPSG:4326 + affine transform, constant across a site's years). We recover the label +georeferencing from the image header. To avoid downloading the 18.4 GB archive (the images +are the bulk and pretraining supplies its own imagery), we range-extract only: (a) each +site's image GeoTIFF header (first 64 KB, enough for CRS+transform+size) and (b) the small +label tifs, then write georeferenced binary raw label rasters to raw/. Total pull ~50 MB. + +Time (spec 5): annual state maps -> 1-year window anchored on each label year; +change_time=null (footprint-mapping/state task, not the dataset's change-detection task). +We DROP the 2015 year (its 1-year window largely predates usable Sentinel-2, which only +began ramping mid/late-2015) and keep 2016-2024 per the Sentinel-era rule. + +Processing (spec 4 dense_raster): scan each raw label in its native EPSG:4326 grid in 64 px +(~640 m) blocks, record class ids present + block-center lon/lat; select tiles-per-class +balanced (rarest first) up to 1000/class under the 25k cap; reproject each selected tile to +a local UTM 64x64 patch at 10 m with NEAREST resampling (categorical); pixels outside the +source site become 255 (nodata).

Extends the Gaofen Image +Dataset (GID/GID-15). 150 Gaofen-2 (GF-2) multispectral scenes (~4 m, ~6900x7300 px) +over China, each with a per-pixel land-cover annotation in a 24-class system, plus an +"unlabeled" (0) class for miscellaneous/unclear areas. Distributed via Google Drive as +several sibling folders; we use only two of them: + * ``Annotation__index`` -> ``{scene}_24label.png`` (single-band uint8 class index) + * ``Coordinate_files`` -> ``{scene}.rpb`` (Rational Polynomial Coeffs) +The 16-bit / 8-bit GF-2 imagery folders are NOT downloaded (pretraining supplies its own +imagery; only the labels + their geolocation are needed). + +GEOREFERENCING (the crux). The distributed label masks are plain **PNG** files with no +CRS/geotransform. The authors instead release per-scene ``.rpb`` files carrying the GF-2 +**RPC00B** rational-polynomial coefficients ("The coordinate information ... is now +available"). We recover geolocation by attaching the RPC to the label grid and warping to +a local UTM projection at 10 m with **nearest** resampling (categorical labels; never +bilinear) via ``rasterio.warp`` (GDAL's RPC transformer, evaluated at the scene's mean +height ``HEIGHT_OFF`` -- no external DEM). RPC-without-DEM geolocation for near-nadir GF-2 +is accurate to ~tens of metres over the mostly-flat annotated regions; this is the sanctioned +metadata-recovery path (task spec triage: "recover geolocation from an accompanying +metadata/RPC/worldfile"). Validated: image centres map to the RPC nominal centre and scene +footprints (~28 km) land correctly in China. + +NATIVE 4 m -> 10 m.

Sampling is tiles-per-class balanced (spec 5): a tile counts toward +every class present, rarer class filled first, up to PER_CLASS tiles/class under the 25k cap. + +Time range: burnt area is a change/event label with a **day-precise ignition date** +(`Start date`), so `change_time` is set to the ignition date and kept as the reference for +building the windows. Instead of a single centered window, we emit two adjacent six-month +windows split at `change_time`: `pre_time_range` (the <=183 days immediately before) and +`post_time_range` (the <=183 days immediately after), with `time_range` set to null (built +via `io.pre_post_time_ranges(change_time, ...)`, spec 5), so pretraining pairs a "before" +image stack with an "after" stack and probes on their difference. The post-fire Sentinel-2 +acquisition (recorded in the shapefile `S2_e`) lands a few weeks after ignition, well +inside the post window. + +Run: python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.floga +""" + +import argparse +import multiprocessing +from collections import defaultdict +from datetime import UTC, datetime +from typing import Any + +import numpy as np +import shapely +import shapely.ops +import shapely.wkb +import tqdm +from rslearn.const import WGS84_PROJECTION +from rslearn.utils.geometry import Projection, STGeometry +from rslearn.utils.mp import star_imap_unordered +from shapely.geometry import box +from shapely.validation import make_valid + +from olmoearth_pretrain.open_set_segmentation_data import ( + download, + io, + manifest, + rasterize, +) + +SLUG = "floga" +NAME = "FLOGA" + +RAW = io.raw_dir(SLUG) +YEARS = [2017, 2018, 2019, 2020, 2021] +ANN_REPO = "Orion-AI-Lab/FLOGA-annotations" +ANN_URL = "https://raw.githubusercontent.com/Orion-AI-Lab/FLOGA-annotations/main" +SHP_EXTS = ["shp", "shx", "dbf", "prj", "cpg"] + +TILE = 64 # output tile edge (px) at 10 m => 640 m +PAD_TILES = 1 # pad the event bbox by this many tiles for unburned context +PER_CLASS = 1000 +MIN_CLASS_PX = 16 # a tile counts toward a class only with >= this many px + +UNBURNED, BURNED = 0, 1 +CLASSES = [ + ( + "unburned", + "Land within the wildfire event's footprint that was not burnt: Sentinel-2 pixel " + "outside the Hellenic Fire Service burnt-area polygon for the event (observed, " + "non-burnt).", + ), + ( + "burned", + "Wildfire burnt area: pixel inside the expert-annotated (Hellenic Fire Service) " + "burnt-area polygon for the Greek wildfire event, at the post-fire Sentinel-2 " + "acquisition.", + ), +] + + +# --------------------------------------------------------------------------- raw download +def _ensure_raw() -> None: + """Download the v2 annotation shapefiles (label-only) into raw_dir; write SOURCE.txt.""" + RAW.mkdir(parents=True, exist_ok=True) + for year in YEARS: + for ext in SHP_EXTS: + fname = f"fb_{year}_final_images_4326.{ext}" + download.download_http(f"{ANN_URL}/polygons/v2/{fname}", RAW / fname) + (RAW / "SOURCE.txt").write_text( + "FLOGA burnt-area labels (v2 polygons) from GitHub Orion-AI-Lab/FLOGA-annotations,\n" + "polygons/v2/fb_{2017..2021}_final_images_4326.shp (EPSG:4326).\n" + "Fields: ID, Year, 'Start date' (ignition), 'End date', S2_s/S2_e (pre/post S2),\n" + "MOD_s/MOD_e, S1_* (candidate SAR).

Each metadata row is one Sentinel-2 composite image for a +facility location, with columns ``category`` (one of 62 functional land-use classes), +``location_id`` (fMoW location index within a category+split), ``image_id`` +(``<100`` = a real fMoW acquisition, ``>=100`` = a synthetic 6-month-interval composite), +``timestamp`` (UTC center of the composite interval), and ``polygon`` (WGS84 lat/long +bbox of the location). Metadata CSVs (train/val/test_gt) are small (~220 MB total); the +77 GB image tarball is NOT downloaded — pretraining supplies its own imagery. + +Encoding decision (spec 2a/4 "scene-level" + task guidance): a fMoW category labels a +**facility at a location** (a golf course, stadium, port, gas station, ...). The bbox is +the facility footprint (median ~0.4 km), and the pixels surrounding the facility are not +reliably the same class, so a uniform-class tile would overclaim. We therefore emit one +**1x1 sparse point classification** label at the facility bbox **centroid** with the +category class, written to a single dataset-wide ``points.geojson`` (spec 2a) rather than +tens of thousands of tiny per-facility GeoTIFFs. The 62 fMoW categories map to class ids +0..61 (descending unique-location frequency; well under the 254-class uint8 cap). + +Deduplication: the raw CSVs are a per-location image time series (882,779 rows over +82,012 locations); we collapse each unique (split, category, location_id) location to ONE +point (the facility land use is static across its time series). Balanced to <=1000/class, +subject to the 25k per-dataset cap (spec 5) => ~403/class effective across 62 classes. + +Time range (spec 5): the facility is a static land use. For each location we pick a +representative **post-2016** image — preferring a real fMoW acquisition (image_id<100), +else a synthetic composite center — and set a 1-year window centered on that acquisition +timestamp (image-acquisition-based ~1-year window). Post-2016 rule: rows before 2016 are +dropped; the 11 locations with no post-2016 image are dropped entirely. + +Note on parallelism: the scan is three bulk CSV reads (not the tens-of-thousands of small +weka files the mp.Pool guidance targets) and the write is a single points.geojson, so +vectorized pandas is used directly; no multiprocessing.Pool is needed here. + +Run: ``python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.fmow_sentinel_functional_map_of_the_world`` +""" + +import argparse +import re +from collections import Counter +from datetime import UTC, datetime + +import pandas as pd + +from olmoearth_pretrain.open_set_segmentation_data import download, io, manifest +from olmoearth_pretrain.open_set_segmentation_data.sampling import balance_by_class + +SLUG = "fmow_sentinel_functional_map_of_the_world" +NAME = "fMoW-Sentinel (Functional Map of the World)" +PER_CLASS = 1000 +STACKS_BASE = "https://stacks.stanford.edu/file/druid:vg497cb6002/" +SPLITS = ["train", "val", "test_gt"] +HALF_WINDOW_DAYS = 180 # +/-180d => 360-day window, within the pretraining cap + +_NUM_RE = re.compile(r"-?\d+\.?\d*") + +# Concise definitions for the 62 fMoW functional/land-use categories (from the fMoW +# challenge taxonomy).

No credential required. +It ships one Excel workbook (FOS_data_v2019.04.10.xlsx) with a "Plots" sheet of 1,645 +sub-plots across 274 plots. Each sub-plot row carries the plot center lon/lat, census +year, plot area, AGB estimates (Mg/ha) under three allometric schemes (local / Chave 2014 +eq.7 / Feldpausch), Lorey's and max canopy height (m), wood density, basal area, stem +density, etc. In this OPEN package coordinates are rounded to 2 decimal places (~1 km at +the equator); the accurately-geolocated version is portal-only (registration). + +REGRESSION TARGET -- plot-mean aboveground biomass (AGB), Mg/ha (= t/ha). +We use AGB_local (local allometric equations / Chave 2014 eq.4 with local H-D curves), +the dataset's most direct estimate. AGB_Chave, AGB_Feldpausch and both canopy-height +metrics are carried per point as auxiliary properties (canopy height is the secondary +quantity noted in the manifest; the regression block holds AGB only). + +Plot-level aggregation (not sub-plot): the OPEN package rounds coordinates to 2 dp, so all +sub-plots of a plot collapse onto the same ~1 km cell (240/274 plots share a single 2dp +coord; up to 136 sub-plots at one coord). Emitting sub-plots would put contradictory AGB +values on the same 10 m pixel, so we aggregate each plot to one point at its center with +the plot-mean AGB (FOS itself recommends "use a plot average" to avoid within-plot spatial +autocorrelation). This yields 247 plots with a valid plot-mean AGB and coordinates. + +Each label is a single point with a continuous value -> REGRESSION written to a +dataset-wide point table (points.geojson, spec 2a), NOT per-point GeoTIFFs. 247 samples is +well under the 5000-sample regression cap, so all valid plots are kept (no downsampling, +no bucket-balancing needed); the AGB distribution is only mildly right-skewed. + +Time range: plots censused 2016+ get a 1-year window on their census year; plots censused +before 2016 (median census ~2010) get a representative Sentinel-era 1-year window (2016, +the earliest full Sentinel-2 year, minimizing the gap to the field measurement). Per the +task, AGB at established permanent research plots is slowly-varying, so anchoring pre-2016 +plots to an early Sentinel window is acceptable -- this is the main caveat (documented in +the summary), alongside the ~1 km coordinate rounding of the open package. + +Run: + python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.forest_observation_system +""" + +import argparse + +import numpy as np +import pandas as pd + +from olmoearth_pretrain.open_set_segmentation_data import download, io, manifest + +SLUG = "forest_observation_system" +NAME = "Forest Observation System" + +DOWNLOAD_URL = "https://pure.iiasa.ac.at/id/eprint/17619/1/FOS_data_v2019.04.10.zip" +ZIP_NAME = "FOS_data_v2019.04.10.zip" +XLSX_REL = "FOS_data_v2019.04.10/FOS_data_v2019.04.10.xlsx" + +# Plots censused in 2016+ use their census year;

We keep both: +class id 0 = not burned (background), class id 1 = burned. + +WHY STATIC PRESENCE, NOT A DATED CHANGE LABEL (spec 5): +GABAM resolves a burn only to the YEAR (the pixel burned sometime during that calendar +year), NOT to within ~1-2 months. A dated change label would require placing the fire +event confidently inside the pretraining pairing window, which we cannot do at year +resolution. Instead we treat a burned pixel as a persistent post-fire burn-scar STATE: +after a fire the scar (charring, vegetation loss) stays visible for many months, so +"burned vs not-burned" is a legitimate static presence classification over a 1-year +window. Therefore change_time = null and time_range = the full GABAM calendar year. +(This is exactly the persistent-post-change-state exception in spec 5.) + +GLOBAL DERIVED PRODUCT -> BOUNDED-TILE SAMPLING (spec 5): +GABAM is global; we do NOT attempt global coverage. We download a bounded set of year +ZIPs and extract a curated set of 5x5-deg source tiles from representative fire-prone +biomes across both hemispheres and several post-2016 years (Sub-Saharan African savannas +- which dominate global burned area - plus South American cerrado/arc-of-deforestation, +northern-Australian savanna, boreal Siberia, western North America, Central-Asian steppe, +mainland SE Asia and the Mediterranean). Only post-2016 years are used (Sentinel era). + +Non-overlapping ~64px-footprint native windows are scanned; a window is a burn candidate +if it is >= BURN_MIN burned (a strong, high-confidence burn-scar signal) and a background +candidate if it is pure not-burned. Windows with a weak/ambiguous burn fraction +(0 < frac < BURN_MIN) are skipped. Tiles-per-class balanced selection (rarest class first) +draws up to 1000 tiles/class. Native 30 m EPSG:4326 windows are reprojected to a local UTM +projection at 10 m with nearest resampling (categorical labels). + +Run: python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.gabam_global_annual_burned_area_map +""" + +import argparse +import multiprocessing +import zipfile +from collections import Counter +from typing import Any + +import numpy as np +import rasterio +import tqdm +from rasterio.warp import Resampling, reproject, transform_bounds +from rasterio.windows import from_bounds +from rslearn.utils.mp import star_imap_unordered +from rslearn.utils.raster_format import get_transform_from_projection_and_bounds + +from olmoearth_pretrain.open_set_segmentation_data import download, io +from olmoearth_pretrain.open_set_segmentation_data.sampling import ( + select_tiles_per_class, +) + +SLUG = "gabam_global_annual_burned_area_map" +ZENODO_RECORD = "13858799" + +PER_CLASS = 1000 +BLOCK = 22 # native (30 m) block ~= 640 m ~= a 64 px @ 10 m UTM tile footprint +TILE = 64 +PRESENT_FRAC = 0.05 # a class is "present" in a window if it covers >= 5% of the block +BURN_MIN = ( + 0.10 # a burn window must be >= 10% burned (high-confidence burn-scar signal) +) + +# Out-of-source fill sentinel (raw GABAM is only 0/1, so 255 is safe as nodata). +SRC_FILL = 255 + +# Curated representative fire-prone source tiles.

These are visible at 10-30 m when the trace is buffered to a + short zone. + + WHY FILTER (much is NOT observable): (1) many faults are blind/buried or have subtle + sub-pixel scarps; (2) OFFSHORE / SUBMARINE fault classes -- oceanic spreading ridges, + subduction megathrust traces at trenches, oceanic transform faults -- are not visible + in land imagery at all; (3) the trace positional accuracy is highly variable: where + recorded, the ``accuracy`` field holds source mapping scales as coarse as 1:100k-1:1M, + i.e. hundreds of metres to kilometres of positional uncertainty, so a rasterized line + may not sit exactly on the imaged feature. + + FILTERS APPLIED: + - LAND MASK: every tile centre must fall on land (Natural Earth 50 m land polygons). + This removes offshore spreading ridges, subduction-trench traces and oceanic + transforms directly -- the strongest observability guard. + - SLIP-TYPE DROP: Spreading_Ridge and Subduction_Thrust (plate-boundary features, not + mapped surface fault traces; overwhelmingly submarine), Blind Thrust (blind by + definition), and the fold axes Anticline / Syncline (folds, not faults, and not in + the slip-type class scheme), plus NULL slip_type, are dropped. + - A wider dilation (2 px, ~40-50 m wide zone) partially absorbs positional error. + + RESIDUAL CAVEATS (see summary): even after filtering, alignment between a rasterized + trace and the imaged geomorphic feature is imperfect (coarse source accuracy), and some + retained continental faults have weak/no 10 m surface expression. Labels are therefore + noisier than field-mapped reference data; downstream assembly filtering + the + positive-only scheme mitigate this. +=================================================================================== + +Class scheme (id = slip-type family). Only surface-observable continental fault +kinematics are kept; the manifest "thrust" class is NOT represented because its only +GEM members are offshore Subduction_Thrust and Blind Thrust (both dropped) -- compressional +faulting is represented by "reverse" (thrust is kinematically a low-angle reverse fault): + + 0 = normal (extensional dip-slip: Normal) + 1 = reverse (compressional dip-slip: Reverse) + 2 = strike-slip (Dextral, Sinistral, Strike-Slip, Dextral/Sinistral Transform) + 3 = oblique (mixed dip-/strike-slip: *-Reverse, *-Normal, *-Strike-Slip combos) + +Non-fault pixels are nodata (255): POSITIVE-ONLY mask (spec S5) -- no fabricated +background class or negatives; the assembly step supplies negatives from other datasets. + +Recipe (spec S4 lines + S5 bounded global product): fault LineStrings are partitioned +onto a ~640 m latitude-aware geographic grid; each occupied on-land cell becomes one +64x64 local-UTM 10 m tile centred on the cell, into which the fault segments in that cell +are rasterized (centreline buffered ~2 px, all_touched). A tile counts toward every +slip-type it contains -> tiles-per-class balanced sampling (rarest class first) to +<=1000 tiles/class, bounding the otherwise global product. + +Time (spec S5, static labels): faults are persistent static features; each tile gets a +static 1-year window (change_time=null) spread deterministically over 2016-2019 for +imagery diversity. + +Run (idempotent; skips already-written tiles): + python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.gem_global_active_faults_database +""" + +import argparse +import math +import multiprocessing +import random +from collections import Counter, defaultdict +from typing import Any + +import numpy as np +import shapely +import shapely.prepared +from rasterio.crs import CRS +from rslearn.utils.geometry import Projection +from rslearn.utils.mp import star_imap_unordered + +from olmoearth_pretrain.open_set_segmentation_data import ( + download, + io, + manifest, + sampling, +) +from olmoearth_pretrain.open_set_segmentation_data.rasterize import ( + geom_to_pixels, + rasterize_shapes, +) + +SLUG = "gem_global_active_faults_database" +NAME = "GEM Global Active Faults Database" + +GEOJSON_URL = ( + "https://raw.githubusercontent.com/GEMScienceTools/gem-global-active-faults/" + "master/geojson/gem_active_faults_harmonized.geojson" +) +GEOJSON_NAME = "gem_active_faults_harmonized.geojson" +LAND_SHP = "ne_50m_land.shp" + +# Source CRS is WGS84 lon/lat degrees.

"Water gain" and "water loss" are **multi-year change classes** defined over the +whole 1999-2021 period with NO precise event date, so they FAIL the ~1-2 month change- +timing rule (spec §5) and cannot be encoded as dated change labels. We therefore drop +gain/loss and build a per-pixel **static classification** from the per-year ``annual +water percent`` layer, which gives exactly the within-year (intra-annual) water state for +a single Sentinel-era reference year: + + percent == 0 -> land (no surface water in any observation that year) + percent 1..99 -> seasonal water (intra-annual variation: present some observations) + percent == 100 -> stable water (water in every valid observation that year) + 255 -> nodata + +Seasonal (intra-annual) water is a valid within-year class; "stable water" here is the +per-year permanent-water state (water all year), consistent with the manifest's stable- +water notion. task_type = classification, 1-year time range anchored on the reference year. + +We evaluated the MANUAL time-series reference sample +(https://glad.geog.umd.edu/timeSeriesReference/timeSeriesSample.zip): it is georeferenced +(600 ~30 m single-pixel polygons, EPSG:4326) but tiny and its per-point ``Stratum`` field +is the map class the point was drawn from (a multi-year stratum incl. gain/loss), not a +clean per-year interpretation. It cannot supply balanced static per-year classes, so we +use the derived annual-percent raster directly (an expert-validated product), sampling only +high-confidence windows -- the same choice made for jrc_global_surface_water. + +Because this is a HUGE global product (each tile is 40000x40000 px), we do BOUNDED-TILE +sampling (spec §5): a handful of representative INTERIOR continental 10x10-deg tiles across +diverse biomes/hemispheres, scanned for non-overlapping ~64px-footprint windows and +selected tiles-per-class (rarest first) up to 1000 tiles/class.

Code + data at +github.com/reglab/aquaculture, archived on Zenodo record 10933921 (v1.0.0).

We grid-snap features to 64x64 (640 m) UTM tiles +keyed by (year, utm_epsg, cell); within a cell-year, manual GT takes precedence over +detections. Per tile we rasterize the cage footprints as class 1 (all_touched, so tiny +cages keep >=1 px), ring each footprint with a 10 px nodata (255) buffer -- coordinates are +ortho-derived and may be a couple px off the Sentinel grid -- and leave the rest of the +tile as background 0. In-tile background provides spatially-meaningful negatives (finfish +farms never fill a 640 m tile); we do NOT fabricate separate all-ocean negative tiles since +"confirmed-empty ocean" cannot be reliably derived from this release.

Polygon Z. + * ``Artisanal and small-scale mine/...shp`` (4,058) and ``Larger scale mine/...gdb`` + (761) — separate ASM / large-scale subsets, not used here (see summary). + +Task: **binary mine-footprint vs background segmentation** (label_type: polygons). + + 0 = background (not a mapped mine) + 1 = mine (inside a Tang & Werner mine-area polygon) + +Why binary: the manifest lists 6 fine mine-feature classes (waste-rock dumps, pits, +ponds, tailings dams, heap leach, processing), but the RELEASED polygons carry NO +per-polygon feature-type attribute. The ``Name`` field is just leftover KML placemark +text (mostly "多边形"/"未命名多边形" = "polygon"/"unnamed polygon", "Placemark", etc.), +not a class code. Per-feature-type classification is therefore not expressible from this +release, so we map to the well-supported binary mine/background signal (mines are large — +median polygon area ~0.12 km^2, i.e. tens of 10 m pixels — clearly observable at 10-30 m +from S2/S1/Landsat). + +We rasterize mine polygons into 64x64 UTM 10 m tiles with the same BOUNDED, geographically +stratified strategy as the GLAKES script (round-robin over 1-degree lon/lat cells), capped +at 25,000 tiles total: + + * positive : centered on a stratified sample of mine-polygon centroids. All Tang & Werner + polygons intersecting the 640 m tile are rasterized to class 1; the rest is + background 0. Large mines fill most of the tile; small mines sit in + background, so positive tiles usually contain both classes. + * negative : background-only tiles, produced by offsetting a stratified sample of mine + anchors by a random ~3-9 km vector so no mine falls in the tile. If the + offset still clips a mapped mine, that mine is simply rasterized correctly + (the tile then counts as a mine tile). + +Per-tile intersecting polygons are read directly from the shapefile with a pyogrio bbox +spatial filter (in the source EASE-Grid CRS, using the .sbn spatial index), so no giant +in-memory STRtree is needed and both scan and write phases parallelize over a Pool. + +Time range: mine footprints are quasi-static (imagery ~2019, manifest window 2016-2019). +Each tile gets a 1-year window with start year uniform in 2016-2019 (Sentinel era). + +Run: ``python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.global_mining_footprint_tang_werner`` +Idempotent: existing ``locations/{id}.tif`` are skipped. +""" + +import argparse +import math +import multiprocessing +import os +import random +from collections import Counter, defaultdict +from typing import Any + +import numpy as np +import tqdm +from rslearn.utils.mp import star_imap_unordered + +from olmoearth_pretrain.open_set_segmentation_data import io + +SLUG = "global_mining_footprint_tang_werner" +NAME = "Global Mining Footprint (Tang & Werner)" +RAW = str(io.raw_dir(SLUG)) +_ARCHIVE_ROOT = os.path.join(RAW, "extract", "Supplementary 1：mine area polygons") +SHP = os.path.join(_ARCHIVE_ROOT, "74548 mine polygons", "74548_projected.shp") +PRJ = os.path.join(_ARCHIVE_ROOT, "74548 mine polygons", "74548_projected.prj") + +# Source CRS WKT (WGS 84 / NSIDC EASE-Grid Global, metres) — read once at import. +with open(PRJ) as _f: + SRC_WKT = _f.read().strip() + +TILE = 64 +POS_TARGET = 20000 +NEG_TARGET = 5000 +CELL = 1.0 # geographic stratification cell size (degrees) +YEARS = [2016, 2017, 2018, 2019] + +CLASSES = [ + ( + "background", + "Not a mapped mine: land or any surface outside a Tang & Werner mine-area polygon.", + ), + ( + "mine", + "Inside a Tang & Werner mine-area polygon: the surface footprint of mining " + "(open-pit/quarry excavations, waste-rock dumps, tailings/ponds, heap-leach and " + "processing areas, etc., undifferentiated), manually contoured from high-resolution " + "satellite imagery (~2019) across 135 countries.", + ), +] +BG, MINE = 0, 1 + + +# --------------------------------------------------------------------------- projections + + +def _src_proj(): + from rasterio.crs import CRS + from rslearn.utils.geometry import Projection + + return Projection(CRS.from_wkt(SRC_WKT), 1, 1) + + +def _to_lonlat(xs: np.ndarray, ys: np.ndarray) -> tuple[np.ndarray, np.ndarray]: + """Vectorized reprojection of EASE-Grid metre coords -> WGS84 lon/lat.""" + from pyproj import Transformer + from rasterio.crs import CRS + + tr = Transformer.from_crs(CRS.from_wkt(SRC_WKT), "EPSG:4326", always_xy=True) + lon, lat = tr.transform(xs, ys) + return np.asarray(lon), np.asarray(lat) + + +# --------------------------------------------------------------------------- scan + + +def load_centroids() -> dict[str, np.ndarray]: + """Read all 74548 polygons once;

A +vector inventory of offshore oil/gas platforms across six major offshore basins (Gulf of +Mexico, Persian Gulf, North Sea, Caspian Sea, Gulf of Guinea, Gulf of Thailand), produced +from satellite (Sentinel-1 SAR) observations.

The first comprehensive global map of +snowmelt *runoff onset* timing: Sentinel-1 C-band SAR (VV) backscatter minima -- which +coincide with the ripening->runoff transition of melting seasonal snow -- detected inside a +custom MODIS-derived snow-phenology search window. Validated against 735 Western-US snow +pillows (median timing difference -1.0 d, MAD 9.0 d). + +This is a REGRESSION target: per-pixel `runoff_onset`, the **day of water year (DOWY)** of +runoff onset, integer 1-366, no-data -9999. Native grid is EPSG:4326 at ~80 m effective +resolution (pixel spacing ~7.2e-4 deg), dims (water_year: 10, lat: 195970, lon: 499998), +signed int16. `runoff_onset` has NO scale factor (integer DOWY); the 0.1 scale factor +documented for the record applies only to the *_mad / temporal_resolution variables, which +we do not use. Water-year definition (from the record): + * Northern Hemisphere: WY N = Oct 1 (N-1) .. Sep 30 (N); DOWY 1 = Oct 1 (N-1). + * Southern Hemisphere: WY N = Apr 1 (N) .. Mar 31 (N+1); DOWY 1 = Apr 1 (N). +Typical runoff onset is DOWY ~110-270 (the product's own colour scale), i.e. the melt event +of water year N falls within **calendar year N** in BOTH hemispheres (NH spring N; SH austral +spring/summer N). So each annual layer is assigned a 1-year time window on calendar year N. + +Sentinel era: the record covers WY2015-2024, but WY2015's melt occurs in spring 2015 (NH) +which is pre-2016. We DROP WY2015 (pre-2016), then from WY2016-2024 sample a bounded, evenly +spaced 5-water-year subset -- WY2016, 2018, 2020, 2022, 2024 -> calendar-year windows 2016, +2018, 2020, 2022, 2024. This bounded temporal sampling keeps the network job inside Zenodo's +guest rate-limit window while still giving 5 distinct 1-year pairing windows per region. + +Access (bounded, spec 5): this is a large global derived product, so we do NOT attempt +global coverage. The record ships a Kerchunk reference file +(`global_snowmelt_runoff_onset.zarr.tar.refs.json`, ~14 MB) mapping each Zarr key to +`[tar_url, byte_offset, byte_length]` inside the single `.zarr.tar` on Zenodo. We use it to +fetch **only the chunks a bounded region touches** via our own HTTP range requests + blosc +decode (chunks are 2048x2048 blosc-zstd int16 blocks) -- we do NOT go through fsspec's +ReferenceFileSystem because zarr v3's store cannot consume a v2 kerchunk reference fs +(async-flag mismatch), and the reference format is trivially direct. We read a curated set of +19 seasonal-snow regions spanning both hemispheres (Western US ranges, Alaska, Canadian +Cordillera, Iceland, European Alps, Scandinavia, Caucasus, Himalaya, Tien Shan, Pamir, Altai, +E. Siberia, Central Andes, Patagonia, Southern Alps NZ) for the 5 sampled water years, +caching each region-water-year to raw/regions/{region}_WY{wy}.tif (EPSG:4326, 80 m, int16, nodata -9999) +so the network is hit once and re-runs are idempotent. NOTE: Zenodo's file CDN fingerprints +the User-Agent (403 "unusual traffic" for non-browser agents), so all Zenodo requests send a +real browser User-Agent. + +Output: single-band **int16** GeoTIFFs, local UTM, 10 m/pixel, 64x64 (~640 m), nodata +**-9999** (the source sentinel; the repo's default -99999 does not fit int16). Each 64x64 +window corresponds to an 8x8 native (80 m) block; the ~80 m source window is reprojected / +resampled from EPSG:4326 to the local UTM tile at 10 m (bilinear over the continuous DOWY +field; a nearest/threshold validity mask is warped alongside so -9999 never blends into +valid pixels, and reprojected values are rounded back to integer DOWY). Windows are +**bucket-balanced** across the DOWY distribution (quantile buckets) to span the melt-timing +range rather than piling up in the seasonal mode.

No +credential required (PANGAEA HTTP; a Firefox User-Agent avoids the UA-fingerprint block). +GLORIA is 7,572 curated in-situ hyperspectral remote-sensing-reflectance measurements from +450 water bodies worldwide, each with at least one co-located water-quality measurement: +chlorophyll-a (Chla), total suspended solids (TSS), CDOM absorption at 440 nm (aCDOM440), +and Secchi disk depth. We use only the ``GLORIA_meta_and_lab.csv`` table (coords + dates + +lab values); the bulky per-wavelength radiometry CSVs are not needed for the label signal. + +REGRESSION TARGET -- chlorophyll-a concentration (Chla, mg m-3). Chla is chosen as the +PRIMARY target because it is the most standard water-quality variable retrievable from +S2/S1/Landsat water color AND the best-populated post-2016 column here (1,635 usable points +vs 1,530 TSS / 1,568 Secchi / 980 aCDOM440).

GRanD as a standalone product has been +*discontinued* and fully integrated into the **Global Dam Watch (GDW) consensus database +v1.0** (Nature Scientific Data 2024, doi:10.1038/s41597-024-03752-9), which is the current, +freely downloadable realization (figshare 25988293, CC-BY-4.0). We therefore download GDW +v1.0 (barriers point layer + reservoirs polygon layer, EPSG:4326) and **scope to GRanD +provenance only** so this dataset stays distinct from the separately-cataloged GOODD +dataset (GOODD contributes ~24k of GDW's barriers; GRanD contributes ~7.4k). + +GRanD subset (ORIG_SRC == 'GRanD' / GRAND_ID > 0): + * 7,424 barrier (dam) points + * 7,378 reservoir polygons (all have a matching GRanD barrier; 46 barriers are dam-only) + +This is a MIXED-MODALITY dataset (reservoir polygons = segmentation, dam points = +detection). Per spec section 5 we combine both into ONE unified class scheme: + + 0 = background (land / other, inside a detection/segmentation tile) + 1 = reservoir (inside a GRanD reservoir polygon; visible water body at 10-30 m) + 2 = dam (barrier point; detection positive, ringed by a nodata buffer) + 255 = nodata/ignore (dam detection buffer ring) + +Encoding: for each GRanD barrier we build a 64x64 (640 m) local-UTM tile at 10 m CENTERED +ON THE DAM POINT (the dam sits at the reservoir margin/outlet, so a dam-centered window +captures reservoir water + surrounding land + the dam structure). All GRanD reservoir +polygons intersecting the tile are rasterized to class 1 (all_touched, invalid rings +repaired via make_valid); then every GRanD dam point in the tile is stamped as a class-2 +positive (1 px) ringed by a 10 px nodata (255) buffer -- dam coordinates are not pixel +exact, so the ring avoids penalizing a few-pixel offset (spec section 4). Background (land) +fills the rest and supplies spatially-meaningful negatives for the dam class, so no separate +negative tiles are fabricated. The 46 dam-only barriers yield background+dam tiles. + +Time range: dams/reservoirs are persistent structures visible throughout the Sentinel era. +Most GRanD dams predate 2016 (YEAR_DAM median unknown/-99).

The Zenodo description lists +them in order; the raster carries exactly the 11 values 0..10, and their global pixel +frequencies are geomorphologically self-consistent with that order (linear / network / +sand-sheet surfaces are extensive; dome and star dunes are rare), so we map value == list +index: + + 0 simple crescentic dunes + 1 compound-complex crescentic dunes + 2 simple linear dunes + 3 compound-complex linear dunes + 4 dome dunes + 5 star dunes + 6 parabolic dunes + 7 dendritic dunes + 8 network dunes + 9 sand sheets (by far the most extensive surface; ~87% of mapped pixels) + 10 others + 255 = nodata / outside the mapped sand domain (kept as CLASS_NODATA) + +This is a per-pixel **classification** dense_raster.

The Hakku file download for this product is +delivered only through an order/checkout flow that submits a customer identity, so we do +NOT use it.

We ``export`` PNG tiles at native 10 m (nearest-neighbour; +verified to render a clean discrete colour set with no interpolation) and decode the +rendered colour back to the raw site-type code. The MapServer's rendered colormap does not +match its REST legend swatches, so the colour->code map was recovered empirically once via +the MapServer ``identify`` operation (cached in raw/{slug}/color_decoder.json).

The parent-image origin is + recoverable (subtract offset*0.3), but the TRUE per-image GSD (0.1-1 m per the paper, + varying scene to scene) is NOT reliably recoverable: single-block parents give no scale + information, and multi-block parents' block-offset naming has ambiguous pixel units. An + assumed GSD would misplace/mis-scale the label on the S2 grid (errors up to ~km for + corner tiles). Rather than emit misregistered labels, the Case-A subset is dropped. + +Consequence/caveat: the processed subset is geographically narrower than the full GTPBD +(Southwest + Central China only), losing the global "Rest of the world" tiles. + +=== CLASS SCHEME (task spec 5 multi-target -> one unified class map) === +GTPBD provides three co-registered label types per tile: mask (terrace area, binary), +boundary (parcel ridge/edge, binary, thin), parcel (parcel interior, binary). At 10 m the +terrace PARCEL AREA (mask) is clearly resolvable (manifest note: terraced hillslopes visible +at 10-30 m), but the boundary/edge ridges are sub-metre (~1-3 native px, <0.3 px at 10 m) and +do not survive mode resampling; the parcel labels are instance-oriented and not a fixed +per-pixel class set. So the unified scheme uses the MASK layer as a per-pixel binary +segmentation: + 0 = background (non-terraced land within the scene) + 1 = terraced parcel +Boundary and parcel layers are NOT encoded (unresolvable / not per-pixel-class at 10 m); +noted in the summary. + +VHR handling (task spec 4 VHR-native): each 512x512 binary mask (WGS84, ~0.5-0.8 m) is +reprojected to a local UTM grid at 10 m with MODE resampling (categorical majority; never +bilinear), yielding one ~23-36 px tile per source tile (all <= 64). Augmented tiles (``_flip`` +/ ``_rot90`` in the filename) are geometric copies of originals and are excluded. + +Time range: no per-tile acquisition date; terraces are static agricultural features (imagery +spans 2016-2025). Treated as static (task spec 5) with a representative 1-year Sentinel-era +window (2020). + +Labels are read directly out of the local HF zip (only ``mask_labels/*.png`` + their +``.aux.xml`` are decoded). Scanned tile records are cached to ``raw/{slug}/scan_cache.pkl``. + +Run: python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.gtpbd_global_terraced_parcel_and_boundary_dataset +""" + +import argparse +import itertools +import math +import multiprocessing +import pickle +import re +import zipfile +from io import BytesIO +from typing import Any + +import numpy as np +import rasterio +import tqdm +from affine import Affine +from PIL import Image +from pyproj import Transformer +from rasterio.warp import Resampling, reproject +from rslearn.utils.geometry import Projection +from rslearn.utils.get_utm_ups_crs import get_utm_ups_projection +from rslearn.utils.mp import star_imap_unordered + +from olmoearth_pretrain.open_set_segmentation_data import io, manifest +from olmoearth_pretrain.open_set_segmentation_data.sampling import ( + MAX_SAMPLES_PER_DATASET, + select_tiles_per_class, +) + +SLUG = "gtpbd_global_terraced_parcel_and_boundary_dataset" +NAME = "GTPBD (Global Terraced Parcel and Boundary Dataset)" +ZIP_NAME = "GTPBD_enhenced_png.zip" +TARGET_RES = 10.0 +PER_CLASS = 1000 +REPRESENTATIVE_YEAR = 2020 +# Below this pixel-size (deg) a GeoTransform is genuine WGS84 degrees (Case-B, correct); +# at/above it the pixel size is the meters-as-degrees units bug (Case-A, rejected). +PX_DEG_MAX = 0.001 + +CLASSES = [ + ( + "background", + "Non-terraced land within the terrace scene: forest, buildings, water, flat fields, " + "bare ground.

Genuine, spatially + meaningful negatives adjacent to the lakes, not fabricated. + 1 = glacial_lake glacial-lake water surface (any of the four Hi-MAG lake types). + +We collapse the four Hi-MAG lake *types* into a single ``glacial_lake`` water class: the +proglacial / supraglacial / unconnected / ice-marginal distinction is defined by a lake's +position/connectivity to its parent glacier (distance, contact), which is not spectrally +separable from a single S2/S1/Landsat tile — so binary water-extent is the well-posed target +(the type attribute is retained in each sample's source_id / summary for provenance). + +Year: we use the **2017** inventory (the most recent Hi-MAG year, post-2016). Glacial lakes +are persistent surface-water bodies, so this is a static label: a representative 1-year +Sentinel-era window (2017), ``change_time=null`` (spec section 5, static labels). The +optional multi-year "change/expansion" variant is deliberately NOT used: Hi-MAG snapshots are +annual, so lake growth is only resolvable to ~a year — too coarse for the <=1-2-month +change-timing rule — whereas the presence/extent state is genuinely persistent. + +Tiling (mirrors the blue-ice-areas dataset): each lake centroid is projected to its local +UTM zone at 10 m and snapped to a 64-px grid; the unique grid cells become candidate tiles, +and every lake polygon intersecting a tile is rasterized into it. Lakes are small relative to +a 640 m tile (median ~0.03 km^2), so most tiles are one lake surrounded by real terrain, with +larger lakes giving lake-dominant interior tiles. We keep one tile per unique grid cell (each +tile contains lake pixels by construction), capped at the 25k per-dataset limit. + +Run (idempotent; skips already-written tiles): + python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.hi_mag_glacial_lakes_high_mountain_asia +""" + +import argparse +import multiprocessing +import random +from collections import Counter +from typing import Any + +import numpy as np +import shapely +import tqdm +from pyproj import Transformer +from rasterio.crs import CRS +from rslearn.utils.geometry import Projection, STGeometry +from rslearn.utils.get_utm_ups_crs import get_utm_ups_projection +from rslearn.utils.mp import star_imap_unordered + +from olmoearth_pretrain.open_set_segmentation_data import io +from olmoearth_pretrain.open_set_segmentation_data.download import download_zenodo +from olmoearth_pretrain.open_set_segmentation_data.rasterize import ( + geom_to_pixels, + rasterize_shapes, +) + +SLUG = "hi_mag_glacial_lakes_high_mountain_asia" +NAME = "Hi-MAG Glacial Lakes (High Mountain Asia)" +ZENODO_RECORD = "4275164" +ZENODO_DOI = "https://doi.org/10.5281/zenodo.4275164" +ZENODO_FILES = ["Hi-MAG database.zip", "Metadata for Hi-MAG database.docx"] + +# The 2017 inventory is the most recent Hi-MAG year (post-2016).

(Maturity/senescence/dormancy are +the other bands and could be emitted as separate regression datasets; we ship greenup onset +per the task instruction.) + +Greenup onset is an ANNUAL per-pixel value, not a dated change event, so change_time is +null and time_range is the 1-year calendar window of the labeled season (2019 or 2020). + +Sampling: bounded-tile sampling across all 156 site-year Date tiles (spec 5), bucket- +balanced across the greenup-DOY value range to <= 5000 samples.

The distribution is a +set of 100 JSON-lines shards; each line is ONE Landsat-8 scene: + + {"filename": "LC08_L1TP_036037_20180406_20180417_01_T1_B10.TIF", + "polygons": [[[x, y], ...], ...], # human contrail annotations + "advected_flight_waypoints": {...}, # (ignored) flight context + "advected_flight_density": [[...]]} # (ignored) flight context + +The ``polygons`` are vertex lists in the pixel grid of the **10x-downsampled** Landsat-8 +thermal band that the labelers viewed (see the released notebook: the false-color image is +``gdal ReadAsArray(buf=shape/10)`` of the 30 m band, so 1 downsampled pixel ~= 300 m). The +dataset itself carries no lon/lat, but each scene's georeferencing is recoverable from the +Landsat-8 L1 MTL metadata on the public bucket ``gs://gcp-public-data-landsat`` (UTM zone, +UL corner projection coords, 30 m thermal grid). We convert every polygon vertex +downsampled-pixel -> scene UTM metres -> WGS84 lon/lat, then rasterize into local-UTM 10 m +label tiles like the other polygon datasets (cf. cal_fire_frap_fire_perimeters.py). + +Task: **binary contrail segmentation** (label_type dense_raster; single manifest class +"contrail"): + + 0 = no_contrail (observed pixel with no contrail annotation) + 1 = contrail (inside a human contrail polygon) + +Each Landsat scene was exhaustively annotated for contrails, so non-contrail pixels are +real observed negatives (as in cabuar_california_burned_areas), not fabricated ones; we +therefore keep a real background class 0 rather than nodata. nodata 255 is reserved/unused. + +Time range: a contrail is a **specific-image** feature valid only at the exact Landsat +overpass (spec §5 specific-image rule), NOT a seasonal/annual label. We set ``time_range`` +to a 1-hour window centered on the scene's DATE_ACQUIRED + SCENE_CENTER_TIME (from MTL) and +leave ``change_time`` null (it is a single-instant presence label, not a change event). All +scenes are 2017-2020 (post-2016), so no pre-2016 filtering is needed. + +Tiling / sampling: contrails span whole 185 km scenes but the label footprint per tile is +capped at 64x64 @ 10 m (640 m). To maximize spatial/temporal diversity of this global +dataset we take, per scene, up to ``N_PER_SCENE`` of its largest contrail polygons as +candidate tiles (each 64x64 tile centered on a polygon centroid, with ALL of that scene's +contrail polygons rasterized into the tile so neighbouring contrails are labeled too), then +select **round-robin across scenes** (one tile per scene per round) up to +``TARGET_SAMPLES`` (1000, the per-class cap for the single "contrail" class). This yields +~1000 tiles drawn from ~1000 distinct scenes. + +Caveat: the annotations were drawn at ~300 m (10x-downsampled 30 m) resolution, so contrail +mask boundaries are coarse (~±300 m) when upsampled to 10 m; the where-mask is valid but +the exact edge is approximate.

Co-registered NEON RGB / LiDAR / +hyperspectral over three NEON sites; the labels are field-mapped **individual tree +crowns** delineated as polygons (``ITC/train_{SITE}.shp``) linked by ``indvdID`` to the +field table ``Field/train_data.csv`` (per-stem ``taxonID`` species code). We use ONLY the +crown geometries + the field species labels -- the multi-GB RemoteSensing imagery is not +needed (pretraining supplies its own imagery). The train release covers two sites: MLBS +(Mountain Lake Biological Station, VA, deciduous forest) and OSBS (Ordway-Swisher +Biological Station, FL, longleaf-pine flatwoods). + +Triage / observability (spec 2 & 8): an individual tree crown is small -- median crown +footprint here is ~4.2 m, i.e. well under one 10 m Sentinel-2 pixel -- so per-crown +species identity is NOT directly resolvable at 10-30 m. This is the same posture as +``globalgeotree`` / ``geolifeclef_geoplant``: because the crowns sit in NATURAL forest +(NEON research sites), a point still acts as a **weak habitat/species label** (the +surrounding canopy correlates with the target), unlike the urban ``auto_arborist`` case +which was rejected (pavement-dominated pixels, no habitat proxy). So we ACCEPT as +weak sparse-point classification and let the downstream assembly step treat/filter it. + +Recipe: sparse points (spec 2a/4). Each crown -> its centroid -> one Point feature with +``label`` = species class id, written to one dataset-wide ``points.geojson`` (NOT per-crown +GeoTIFFs; a crown is a sub-pixel 1x1 label). Class level = ``taxonID`` species code (33 +codes, a few genus-level e.g. Betula sp.); this is far under the 254-class uint8 cap so we +keep every class (ids 0..N-1 by descending frequency). Long-tailed distribution is fine -- +the assembly step drops too-small classes (spec 5), not this script. + +Time range: a tree's species is effectively static; the competition field/flight campaign +is 2018 (manifest time_range 2018-2019, post-2016).

Rasterizing once (rather than re-rasterizing the AOI's tens of +thousands of flood/hydro polygons per window) is what keeps huge AOIs fast.

We use the **Sentinel-2 depth +patches** (``{area}/depth/s2/depth_{id}.tif``) because they are already single-band +GeoTIFFs in a local UTM projection at 10 m/pixel (18x18) -- exactly our target grid, so +no resampling is needed. Depth values are the SfM-MVS + reference-LiDAR/echosounder DSM, +in metres, referenced to the sea surface: **negative = below the water surface (deeper); +small positive values at Puck Lagoon = emergent/near-shore land in the DSM.** The fill +value 0.0 (no reference / masked) is mapped to REGRESSION_NODATA (-99999). + +We take the **annotated bathymetry patches** listed in ``{area}/s2_split_bathymetry.txt`` +(train + test union; all splits are fair game as pretraining labels, spec 5): 35 for Agia +Napa + 2822 for Puck Lagoon = 2857 total, comfortably under the 5000-sample regression cap, +so ALL are used (no sub-sampling, no bucket balancing). + +Depth is a quasi-static seabed quantity, not a dated change event, so change_time is null +and each patch gets a 1-year window anchored on its S2 acquisition year (spec 5, static / +annual labels): Agia Napa S2 = 2016-01-10 -> 2016; Puck Lagoon S2 = 2021-04-20 -> 2021. +(Agia Napa's aerial/LiDAR reference is 2015, but the co-registered S2 image -- what +pretraining pairs against -- is Jan 2016, i.e. Sentinel-era, and the seabed is static.) + +Georeferencing: source patches are already UTM 10 m (Agia Napa EPSG:32636 = WGS84 UTM 36N; +Puck Lagoon EPSG:25834 = ETRS89 UTM 34N, <1 m from WGS84). We REUSE the source CRS (spec +2 allows this) and snap the origin to the integer 10 m pixel grid (<= half-pixel, <=5 m +shift), writing values as-is with no resampling. + +Output: single-band float32 GeoTIFFs, local UTM, 10 m/pixel, 18x18, nodata -99999. + +Reproduce: + python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.magicbathynet +""" + +import argparse +import multiprocessing +import re +from collections import Counter +from typing import Any + +import numpy as np +import rasterio +import tqdm +from rslearn.utils.geometry import Projection +from rslearn.utils.mp import star_imap_unordered + +from olmoearth_pretrain.open_set_segmentation_data import io, manifest +from olmoearth_pretrain.open_set_segmentation_data.download import download_http + +SLUG = "magicbathynet" +NAME = "MagicBathyNet" +URL = "https://zenodo.org/records/16753753" +ZENODO_RECORD = "16753753" +ZIP_NAME = "MagicBathyNet.zip" +ZIP_URL = f"https://zenodo.org/api/records/{ZENODO_RECORD}/files/{ZIP_NAME}/content" + +# Per-area S2 acquisition year (anchors the 1-year static-label window). +AREA_YEAR = {"agia_napa": 2016, "puck_lagoon": 2021} + +MAX_SAMPLES = 5000 # regression cap (spec 5) + + +# --------------------------------------------------------------------------- +# Download + selective extraction +# --------------------------------------------------------------------------- +def raw_root(): + return io.raw_dir(SLUG) + + +def extracted_dir(): + return raw_root() / "extracted" / "MagicBathyNet" + + +def download_and_extract() -> None: + """Download the Zenodo zip (5.9 GB) and extract only the S2 depth patches + splits.""" + import zipfile + + io.check_disk() + raw = raw_root() + raw.mkdir(parents=True, exist_ok=True) + zip_path = raw / ZIP_NAME + if not zip_path.exists(): + print(f"downloading {ZIP_URL}") + download_http(ZIP_URL, zip_path) + io.check_disk() + + ext = extracted_dir() + # Idempotent: skip if a marker area folder already extracted. + if (ext / "agia_napa" / "s2_split_bathymetry.txt").exists(): + print("already extracted") + return + print("extracting S2 depth patches + split files ...") + with zipfile.ZipFile(zip_path.path) as z: + members = [ + n + for n in z.namelist() + if not n.endswith("/") + and (("/depth/s2/" in n) or n.endswith("_split_bathymetry.txt")) + ] + z.extractall(path=(raw / "extracted").path, members=members) + print(f"extracted {len(members)} files") + + +# --------------------------------------------------------------------------- +# Scan: build one record per annotated bathymetry patch +# --------------------------------------------------------------------------- +def _parse_annotated_ids(area: str) -> list[str]: + """Return the patch ids in the 'annotated sample' list of s2_split_bathymetry.txt.""" + p = extracted_dir() / area / "s2_split_bathymetry.txt" + txt = p.read_text() + # The file has several labelled Python-list blocks;

The release ships 1381 patches, each a 256x256 +Sentinel-2 crop already georeferenced in local UTM at 10 m/pixel, with a companion +``*_cl.tif`` class raster (float32; value 0 = unlabeled, 1-15 = the 15 MARIDA classes) +and a ``*_conf.tif`` confidence raster.

Sampling is +tiles-per-class balanced (each tile counts toward every class present in it). The full +candidate set is only 3322 tiles (well under the 25k cap and the 1000/class target for +all but Marine Water), so we keep all of them to maximize coverage of the rare debris +classes; this is the tiles-per-class-balanced outcome with no truncation needed. + +Each patch is a single Sentinel-2 acquisition whose date is encoded in the scene name +(``S2_dd-mm-yy_TILE``).

The core ground- +truth layer ``vw_site_survey_poly`` contains **4,934 georeferenced polygons** delineating +the contours of known archaeological mound sites ("tells"), each confirmed by ground +survey / surface-scatter study across 16 published survey projects.

Instead of a single centered window, we emit two adjacent six-month windows +split at ``change_time``: ``pre_time_range`` (the <=183 days immediately before) and +``post_time_range`` (the <=183 days immediately after), with ``time_range`` set to null. The +windows are built via ``io.pre_post_time_ranges(change_time, ...)``, so pretraining pairs a +"before" image stack with an "after" stack spanning the fire and probes on their difference. +Only fires with ig_date year in 2016-2024 (Sentinel era AND covered by a downloaded +mosaic) are used; pre-2016 perimeters are filtered out, and 2025+ (no mosaic) are dropped. + +Tiling: a fire fitting in a 64x64 tile (640 m) yields one centered tile; larger fires are +gridded into non-overlapping 64x64 windows, keeping windows intersecting the perimeter and +sampling up to MAX_TILES_PER_FIRE per fire.

Distributed via +Figshare (collection 5884598) and intertidal.app. A supervised per-pixel classification +of the Landsat archive over the global coastline (60S-60N) at 30 m, in 3-year epochs. + +IMPORTANT (data reality vs manifest): the manifest lists three classes +[tidal flat, permanent water, other], but the *distributed* v1.2 classification raster is +a BINARY tidal-flat mask -- confirmed empirically across all 108 global tiles: the only +pixel values present are {0, 1}, where 1 = tidal flat and 0 = everything else (permanent +water and other land cover are NOT separated in the published GeoTIFF; this matches the +Earth Engine catalog, whose classification band is bit 0 = intertidal/non-intertidal). +We therefore produce a **2-class** classification: id 0 = tidal flat, id 1 = other +(non-tidal-flat, i.e. permanent water + all other cover merged). See summary/QUESTION. + +We use the **2017-2019 epoch** (latest, matching manifest range 2016-2019).

CRS varies by source region (local UTM zones, EPSG:3857 Web Mercator, +EPSG:4326 geographic, national grids like EPSG:31256/custom Transverse-Mercator WKT), all +with genuine real-world coordinates (verified across kagera/accra/chisinau/coxsbazar/ +houston/jeremie/pomorskie/rotterdam/santa_rosa/shanghai/vienna).

The polygon vectors are also +rasterized to an **ice-wedge-polygon coverage-density** raster: each cell's value is the +fraction of the cell area occupied by ice-wedge polygons. + +Why regression (not the manifest's low-/high-centered classes): individual polygons are +~10-20 m and are NOT reliably resolvable as objects at 10-30 m Sentinel-2 / Landsat, and the +publicly-served raster product is a **single-band coverage-density** layer (it does not carry +a per-cell low-centered vs high-centered microtopography split; that attribute lives only in +the per-polygon geopackage). Per the manifest note ("Use rasterized density at S2/Landsat +scale"), we therefore build a per-pixel **regression** target = ice-wedge-polygon coverage +density (fraction 0-1) at 10 m -- capturing polygon presence/density, which IS observable as +patterned-ground texture at S2/Landsat scale. + +Access / bounded download (this is a huge, >1B-object pan-Arctic product -- we do NOT bulk +download it): the coverage-density GeoTIFFs are published as a WorldCRS1984Quad tile pyramid +(EPSG:4326) at http://arcticdata.io/data/10.18739/A2KW57K57/iwp_geotiff_high/WGS1984Quad/ +{z}/{x}/{y}.tif, zoom levels 0-15. We use **zoom 14** as the density source: it is a +properly *averaged* overview at ~4.8 m/px (lat) / ~1.6 m/px (lon) at 70N, with values that +are genuine area fractions (z=15 is the ~2.4 m native level; z=13 and coarser are *summed* +overviews whose values are inflated >>1, so we avoid them). We download z=14 tiles only over +a bounded set of ~10 representative high-IWP tundra regions across Alaska, Arctic Canada, and +Siberia (§5 large-global-product bounded sampling), mosaic each region, reproject to local +UTM at 10 m with **average** resampling (continuous fraction field; nodata-aware so unmapped +gaps stay nodata), clip the fraction to [0, 1] (values >1 are duplicate-scene overlap +artifacts), and cut 64x64 (~640 m) windows. + +Output: single-band float32 GeoTIFFs, local UTM, 10 m/pixel, 64x64, nodata -99999 +(io.REGRESSION_NODATA).

Per spec 5 we use the change_time +scheme: each sample's ``change_time`` is the polygon's ``image_date`` (day-precise, well +within the required ~1-2 month timing precision), which splits the sample into two adjacent +six-month windows (via ``io.pre_post_time_ranges``): ``pre_time_range`` = the ~6 months +(<=183 days) immediately before the clear-cut and ``post_time_range`` = the ~6 months +(<=183 days) immediately after, with ``time_range`` = null. The label is a **mask of where** +the clear-cut happened. A completed clear-cut persists in imagery, so the pre/post split at +the confirmation date is well-posed for change pairing (before vs after). + +Post-2016 rule: we keep only polygons whose ``image_date`` is on/after 2016-01-01 (the +Sentinel era). PRODES-year-2016 polygons imaged in late 2015 are dropped. + +Encoding (spec 4 polygons, mirroring the DETER-B recipe): for each selected polygon center +a 64x64 UTM 10 m tile on the polygon centroid, rasterize that polygon (all_touched so small +polygons register) as class id 1 (deforestation), background 0 elsewhere. To keep visible +background context (and avoid pathological giant polygons filling the whole tile) we select +polygons with 0.002 <= area_km <= 0.4 km^2 (a 640 m tile is 0.41 km^2). Only the target +polygon is drawn; any co-located clear-cut of another date is left as background. + +Class scheme (uint8): + 0 background (no clear-cut in this pixel: standing forest / other cover) + 1 deforestation (PRODES clear-cut / corte raso) + +Up to TARGET_PER_CLASS tiles for the deforestation class, sampled round-robin across +PRODES years for temporal diversity and across states for spatial diversity (spec 5). +""" + +import argparse +import json +import multiprocessing +import random +import urllib.parse +import urllib.request +from collections import Counter, defaultdict +from datetime import UTC, datetime +from typing import Any + +import shapely +import tqdm +from rslearn.const import WGS84_PROJECTION +from rslearn.utils.mp import star_imap_unordered +from shapely.geometry import shape + +from olmoearth_pretrain.open_set_segmentation_data import io +from olmoearth_pretrain.open_set_segmentation_data.rasterize import ( + geom_to_pixels, + rasterize_shapes, +) + +SLUG = "prodes_brazilian_amazon_deforestation" +NAME = "PRODES (Brazilian Amazon deforestation)" +URL = "https://terrabrasilis.dpi.inpe.br/downloads/" +WFS = "https://terrabrasilis.dpi.inpe.br/geoserver/ows" +LAYER = "prodes-legal-amz:yearly_deforestation" + +TILE = 64 # 64 px @ 10 m = 640 m +BACKGROUND_ID = 0 +DEFOR_ID = 1 +TARGET_PER_CLASS = 1000 +FETCH_PER_QUERY = 80 # candidates fetched per (state, year) +YEARS = list(range(2016, 2026)) +# Legal Amazon states. +STATES = ["AC", "AM", "AP", "MA", "MT", "PA", "RO", "RR", "TO"] +AREA_MIN_KM = 0.002 # ~0.2 ha -> registers at 10 m +AREA_MAX_KM = 0.4 # < 640 m tile (0.41 km^2) so background context remains +MIN_IMAGE_DATE = "2016-01-01" # post-2016 / Sentinel era +SEED = 42 +WINDOW_HALF_DAYS = 180 # +/- 180 d -> 360-day time range centered on image_date + +CLASS_DEFS = [ + ( + 0, + "background", + "No PRODES clear-cut in this pixel: standing forest, previously-cleared " + "land, water, or other cover within the tile.", + ), + ( + 1, + "deforestation", + "PRODES annual clear-cut deforestation (corte raso / DESMATAMENTO): complete " + "removal of primary forest confirmed by expert photointerpretation in the " + "Brazilian Legal Amazon.

This is DAY-precise, well within the + spec's ~1-2 month change-timing requirement. +A per-geography ``forest_baseline`` image (band ``constant`` = 1 over the primary-forest +baseline extent, masked elsewhere) delimits the valid forest area. + +This is a genuine dated CHANGE dataset (forest -> disturbed). Per spec §5 we use the +change_time scheme: each disturbance tile's ``change_time`` is the representative (median) +decoded disturbance date of the confirmed alerts forming a single temporally-coherent event +within the tile. That ``change_time`` splits the tile into two adjacent six-month windows +(via ``io.pre_post_time_ranges``): ``pre_time_range`` = the ~6 months (<=183 days) +immediately before it and ``post_time_range`` = the ~6 months (<=183 days) immediately after, +with ``time_range`` = null. The label is a **mask of where** the disturbance occurred, and +pretraining pairs the "before" image stack with the "after" stack and probes on their +difference. + +Label scheme (uint8, single band, local UTM 10 m): + 0 stable forest (forest-baseline pixel with no alert) -- background. + 1 disturbance (confirmed alert, Alert==3, whose decoded date lies within the tile's + event window [change_time ± EVENT_HALF_DAYS]). + 255 nodata/ignore (outside the forest baseline; low-confidence alerts (Alert==2); + confirmed alerts of a *different* date than this tile's event). + +Only confirmed (high-confidence, Alert==3) alerts define the positive class; low-confidence +alerts are ignored (255) to keep the change mask clean. Disturbance tiles require at least +MIN_DISTURBED confirmed in-window pixels so the mask carries real signal. We also emit +stable-forest background negatives (all class 0 within the forest baseline, no alert) with +``change_time=null`` and a static representative 1-year window. + +Post-2016 rule: RADD begins ~2019 (S. America/Asia baseline 2019, Africa 2018), so every +alert is well inside the Sentinel era; no pre-2016 filtering is needed. + +Access: Earth Engine service-account credentials from ``.env`` +(spec §8 authorizes ``.env`` creds; the GFW data-lake S3 mirror is requester-pays). We do +NOT bulk-download the pan-tropical tiles: candidate centers are sampled with EE +``stratifiedSample`` over a grid of 2° cells across each geography, then each ≤64×64 label +patch is fetched directly (reprojected to local UTM at 10 m, nearest-neighbour) via +``ee.data.computePixels``. + +Run: ``python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.radd_forest_disturbance_alerts`` +Idempotent: candidate samples are cached to raw/, and existing locations/{id}.tif are skipped. +""" + +import argparse +import json +import multiprocessing +import random +import time +from collections import Counter, defaultdict +from datetime import UTC, datetime, timedelta +from typing import Any + +import numpy as np +import tqdm + +from olmoearth_pretrain.open_set_segmentation_data import io + +SLUG = "radd_forest_disturbance_alerts" +NAME = "RADD Forest Disturbance Alerts" +URL = "https://data.globalforestwatch.org/datasets/gfw::deforestation-alerts-radd/about" +EE_COLLECTION = "projects/radar-wur/raddalert/v1" +GEE_KEY = "/etc/credentials/gcp_credentials.json" + +# Three main RADD geographies -> friendly region names. +REGIONS = { + "sa": "Amazon / South America", + "africa": "Congo Basin / Africa", + "asia": "Insular Southeast Asia", +} +# Forest-focused bounding boxes (lon_min, lat_min, lon_max, lat_max) per geography; we grid +# these into CELL-degree cells for spatially-distributed sampling.

We use the **glacier product (G)** -- individual, manually +delineated glacier outline polygons. It is distributed as one zipped ESRI shapefile per +first-order region (19 regions, ~274k glaciers globally), each in EPSG:4326, downloaded +over HTTP from the NSIDC DAAC (NASA Earthdata / URS OAuth; credentials from +.env -> ~/.netrc). + +Task: **binary per-pixel segmentation, glacier vs background.** + 0 background -- non-glacier terrain (rock, snow-free ground, water, vegetation) + 1 glacier -- inside an RGI glacier outline +The glacier outline is a true boundary against *observable* non-glacier terrain, so this +is a genuine two-class segmentation (not a positive-only presence mask). Each tile is +rasterized with ALL glacier polygons intersecting it (via a spatial index), so adjacent +glaciers in the same tile are correctly labeled -- not just the one the tile is centered +on. + +Why not terminus type: the manifest notes "glacier (with terminus-type attributes)", but +in RGI 7.0 the `term_type` attribute is "not assigned" (code 9) for 99.4% of glaciers +(only 1561 of 274531 carry a real terminus code), so it cannot support a class scheme. +We record `term_type` per sample (source_id) for provenance instead. + +Sampling (bounded regional, spec 5): glaciers >= 0.1 km^2 (drops sub-resolution slivers +and improves temporal stability) are sampled round-robin across all 19 regions for +geographic diversity, up to 1000 glacier-centered tiles (the per-class cap; background +co-occurs in most tiles). Each glacier's centroid (cenlon/cenlat) is the tile center; the +64x64 UTM 10 m window spans 640 m so small glaciers show their boundary against background +while large glaciers yield glacier-filled tiles. + +Time range (spec 5, static/persistent label): RGI 7.0 is the nominal-2000 inventory -- +outline source dates are ~99.9% pre-2016 (mean year 2001).

The original outline source date (RGI2000 acquisition year) is +recorded per sample in source_id. Caveat: glaciers -- especially small ones -- have +retreated somewhat since ~2000, so a 2020 image may show a modestly smaller glacier than +the RGI2000 outline; the >= 0.1 km^2 floor limits (but does not eliminate) this mismatch. +""" + +import argparse +import multiprocessing +import os +import random +import warnings +from collections import Counter, defaultdict +from typing import Any + +import numpy as np +import tqdm +from rslearn.utils.geometry import Projection +from rslearn.utils.mp import star_imap_unordered + +from olmoearth_pretrain.open_set_segmentation_data import download, io +from olmoearth_pretrain.open_set_segmentation_data.rasterize import ( + geom_to_pixels, + rasterize_shapes, +) + +warnings.filterwarnings("ignore") + +SLUG = "randolph_glacier_inventory_rgi_7_0" +NAME = "Randolph Glacier Inventory (RGI 7.0)" +RAW = io.raw_dir(SLUG) + +NSIDC_BASE = ( + "https://daacdata.apps.nsidc.org/pub/DATASETS/nsidc0770_rgi_v7/" + "regional_files/RGI2000-v7.0-G" +) + +REGIONS = [ + "01_alaska", + "02_western_canada_usa", + "03_arctic_canada_north", + "04_arctic_canada_south", + "05_greenland_periphery", + "06_iceland", + "07_svalbard_jan_mayen", + "08_scandinavia", + "09_russian_arctic", + "10_north_asia", + "11_central_europe", + "12_caucasus_middle_east", + "13_central_asia", + "14_south_asia_west", + "15_south_asia_east", + "16_low_latitudes", + "17_southern_andes", + "18_new_zealand", + "19_subantarctic_antarctic_islands", +] + +GLACIER_CLASS = 1 +BACKGROUND_CLASS = 0 +PER_CLASS = 1000 +TILE = 64 +YEAR = 2020 +MIN_AREA_KM2 = 0.1 # drop sub-resolution slivers;

RiverScope is a global-scale, +expert-labeled water-segmentation dataset built on PlanetScope imagery (3 m, +BGR+NIR) and co-registered with Sentinel-2, SWORD and SWOT. It ships 1,145 tiles +with predefined train/valid/test splits (splits are spatially disjoint by +location).

Task is dense per-pixel +**CLASSIFICATION** (river vs other water vs background). RiverScope also carries +SWORD/SWOT node widths for width estimation, but the dense raster we consume is +the water-class mask, so we treat it as classification, not width regression. + +Processing (label_type = dense_raster, VHR-native 3 m -> spec §4): each label +GeoTIFF is reprojected once to its local UTM zone at 10 m with **nearest** +resampling (categorical; never bilinear) and cut into 64x64 tiles. A 500x500 3 m +crop (~1.5 km) yields a ~150x150 px 10 m array -> a handful of 64x64 tiles. +Sampling is **tiles-per-class balanced** (spec §5): a tile counts toward every +class present in it (>= MIN_CLASS_PX px); rare classes (river / other water) are +filled first up to PER_CLASS tiles. Background co-occurs in nearly every tile so +it needs no dedicated pass. All three source splits are used (spec §5). + +Time range: each label is the water extent at one PlanetScope acquisition. The +PlanetScope id begins with the acquisition date (YYYYMMDD). Water extent is +seasonally variable, so we anchor a 1-year window centered on the acquisition +date (spec §5, seasonal/annual).

From the 2015 edition on, the "RPG 2.0" product carries +the crop type down to the individual **parcelle** level: each parcel polygon has a 3-letter +``CODE_CULTU`` (detailed crop code, ~300 nationally) and a numeric ``CODE_GROUP`` (grouped +crop, ~28 groups). This is the largest single-country LPIS and is the annual, national +analogue of the EuroCrops snapshots -- so this script mirrors ``eurocrops.py``. + +RPG is huge (national, ~9.5M parcels/year). We download a **bounded, geographically +diverse subset of administrative regions** for one recent snapshot year (2022, within the +manifest's 2016-2024 range), covering all French agroclimatic zones and every major crop: + + R24 Centre-Val de Loire (Beauce cereals, rapeseed), R32 Hauts-de-France (sugar beet, + potato, wheat, flax), R44 Grand Est (Champagne/Alsace vineyards, sugar beet, wheat), + R53 Bretagne (maize, grassland, vegetables), R75 Nouvelle-Aquitaine (maize, sunflower, + vineyard), R76 Occitanie (durum wheat, vineyard, orchards, sunflower), R84 + Auvergne-Rhone-Alpes (grassland, orchards, maize), R93 PACA (vineyard, orchards, rice in + the Camargue, lavender). + +Task: per-pixel **classification** (crop type). Each selected parcel is rasterized into a +<=64x64 local-UTM 10 m tile: the parcel's ``CODE_CULTU`` class id is burned inside the +polygon, everything outside is nodata (255) -- we only have a ground-truth crop label +inside declared parcels, so outside is "ignore", not a background class (spec 5). + +Classes are the distinct ``CODE_CULTU`` codes present in the sampled parcels. Labels are +uint8 (ids 0-253, 255=nodata) so at most 254 classes: if more than 254 codes appear we keep +the top 254 by global frequency and drop the rest (logged). Class ids are assigned 0..N-1 in +descending global frequency. Names come from the IGN/etalab RPG culture nomenclature +(CODE_CULTU -> French libelle); the RPG crop-group name is attached as the class description. + +Sampling: tiles-per-class balanced with the 25k per-dataset cap.

A global dataset for semantic segmentation +of water bodies from Sentinel-1 and Sentinel-2.

Sentinel-1 SAR lake-ice / +water semantic segmentation over four Swiss Alpine lakes across two winters (2016-17, +2017-18). + +What the source provides that we use (all inside the GitHub repo, small text/vector files): + * data/gt/{2016_17,2017_18}/{sihl,sils,silvaplana,stmoritz}.txt -- per-lake, per-DAY + whole-lake state labels from daily webcam observation (semi-automated ground truth). + Each day the whole lake is assigned one state code: + s = snow on ice, lake frozen ~90-100% -> FROZEN (ice) + i = ice, lake frozen ~90-100% -> FROZEN (ice) + w = water, lake ~90-100% open water -> NON-FROZEN (water) + ms/mi/mw (60-90% partial), c (cloud/fog), + u (unclear), n (no data), and any composite -> EXCLUDED (ambiguous) + Only the three unambiguous ("clean") codes {s, i, w} are used, matching the paper's + use of clearly-frozen / clearly-open days. The whole-lake state is propagated to every + pixel inside the lake polygon (this is exactly how the paper builds its per-pixel GT). + * data/shapes/UTM32N.shp -- lake-outline polygons (EPSG:32632). The four labelled lakes: + stmoritz -> "Lej da San Murezzan" (0.75 km2) + silvaplana -> "Lej da Silvaplauna" (2.66 km2) + sils -> "Lej da Segl" (4.09 km2) + sihl -> "Sihlsee" (10.49 km2) + +The Sentinel-1 SAR rasters themselves are NOT needed here: OlmoEarth pretraining supplies +Sentinel-1 imagery independently and pairs it with these labels by geography + time. (The +authors' polybox link that hosted the S1 rasters is dead / 404 as of processing, but that +only held imagery, not labels, so it does not block us.) + +Task: **dense_raster, binary classification** (label_type: dense_raster): + 0 = frozen (ice) (lake surface frozen: ice or snow-on-ice) + 1 = non-frozen (water) (open water) + 255 = nodata/ignore (pixels outside the lake polygon) + +Each sample is a <=64x64, 10 m, UTM (EPSG:32632) tile covering part of one lake on one +clean-state day: pixels inside the lake polygon carry that day's class, pixels outside are +255. Lakes larger than a 640 m tile are covered by a fixed grid of 64x64 tiles (only tiles +with >=5% lake coverage are kept). A given lake-day contributes all of its kept tiles. + +Sampling (spec 5, tiles-per-class balanced, <=1000/class): the four lakes are balanced by +allocating ~250 samples per (lake, class); the number of clean days drawn per lake is +ceil(250 / n_tiles_for_lake), evenly spaced across that lake's sorted clean-day list, and +every kept tile of a selected day is emitted. A final balance_by_class(per_class=1000) caps +each class at 1000 while preserving the cross-lake / cross-date spread. Result ~2000 tiles. + +Time range (spec 5): lake-ice presence is a specific-date / seasonal STATE, so each sample +gets a TIGHT 1-day window [obs_day 00:00 UTC, obs_day+1 00:00 UTC) anchored on the webcam +observation date, with change_time=null (a per-date state, not a dated change event). The +webcam observation date is used as the source acquisition date because the exact per-scene +S1 acquisition timestamps were only in the (now-unavailable) polybox raster share; +downstream assembly pairs the label with whatever S1 scene falls in the window (the frozen / +open state persists across neighbouring days, so a 1-day anchor is temporally coherent). + +Run: python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.sentinel_1_lake_ice_detection +Idempotent: existing locations/{id}.tif are skipped. +""" + +import argparse +import math +import multiprocessing +import re +from collections import Counter, defaultdict +from datetime import UTC, datetime, timedelta +from typing import Any + +import numpy as np +import tqdm +from rslearn.const import WGS84_PROJECTION +from rslearn.utils.mp import star_imap_unordered + +from olmoearth_pretrain.open_set_segmentation_data import io, manifest, sampling +from olmoearth_pretrain.open_set_segmentation_data.rasterize import ( + geom_to_pixels, + rasterize_shapes, +) + +SLUG = "sentinel_1_lake_ice_detection" +NAME = "Sentinel-1 Lake Ice Detection" + +RAW_BASE = "https://raw.githubusercontent.com/prs-eth/sentinel_lakeice/master" +WINTERS = {"2016_17": 2016, "2017_18": 2017} #

A benchmark for population estimation over 98 European cities. The +population reference is the EU GEOSTAT 1 km population grid (2011 census, EPSG:3035 +ETRS89-LAEA Europe); each 1x1 km grid cell carries an absolute population count (persons +living in that km^2) and a log2-binned population class. The dataset also ships Sentinel-2 +seasonal mosaics (2016), LCZ, land use, nightlights, DEM and OSM patches per cell, but +those are pretraining *inputs* we do not need -- we only need the population LABEL. + +Task decision -- REGRESSION on population density (persons/km^2). The source provides both +the continuous population count and a discrete class bin per cell; population is naturally a +regression target and the continuous count is strictly more informative, so we regress it. +Because each cell is exactly 1 km^2, the per-cell count IS a population density in persons +per square kilometre -- a resolution-invariant intensity -- so it can be written to a tile +of any size without a count/area rescale (same unit/convention as +``worldpop_global_population_density``). We fill each output tile uniformly with the cell's +density (the product gives one value per 1 km cell). + +Georeferencing (recoverable, label-only): each populated cell's ``GRD_ID`` is a GEOSTAT/ +INSPIRE LAEA grid name ``1kmN{north_km}E{east_km}`` giving the lower-left corner in EPSG: +3035 (north_km/east_km are in km). Cell centre = (east_km*1000+500, north_km*1000+500); +reproject 3035 -> WGS84 to place the tile on a local UTM grid. Cells that are NOT on the +population grid (uninhabited filler patches) carry a plain numeric id and POP=0 instead of a +``1kmN...`` name -- they have no recoverable coordinates and no population signal, so they +are skipped (the assembly step supplies negatives from other datasets, spec 5). + +Download strategy (label-only; NO imagery pulled): Part1 is distributed as a single ~103 GB +``So2Sat_POP_Part1.zip`` on the mediaTUM WebDAV/dataserv share (public creds m1633792 / +m1633792, also published for rsync). The per-city population CSVs (``{city}/{city}.csv``, +one per city, 98 total, a few KB-90 KB each) live inside that zip. We read the zip's central +directory over HTTP Range requests and extract ONLY those 98 CSVs -- never touching the ~96 +GB of imagery/aux patches. (mediaTUM mishandles a degenerate ``bytes=0-0`` probe by +streaming the whole file; download.HttpRangeFile now streams the probe so this is safe.) + +Time range: population is a persistent/slowly-varying attribute of built structure and the +dataset was assembled to pair with the 2016 Sentinel-2 mosaics, so we treat it as a static +label and anchor a 1-year window at 2016 (spec 5 static-label rule; Sentinel era).

Zenodo record 5642755 (DOI 10.5281/zenodo.5642755), license CC-BY-4.0. A +continent-scale inventory of ~10,500 supraglacial lakes and channels delineated from +January-2017 Landsat 8 and Sentinel-2 imagery (semi-automated classification + manual +post-processing) across the West Antarctic Ice Sheet and Antarctic Peninsula. + +The Zenodo record is dominated by ~190 raw Landsat-8 / Sentinel-2 scene archives +(~130 TB total) that pretraining does NOT need — it supplies its own imagery. All the +label geometry we need lives in a single 17 MB file, ``WAIS_Max_Extent.zip``, which holds +``WAIS_Jan_2017_Polygons.shp`` (10,478 features; also as GeoJSON/KMZ). We download only +that file. Per-feature attributes: ``Feature_Cl`` (Lake / Channel), ``POLY_AREA``, +``Location`` (Ice Shelf / Grounded Ice / Crosses GL), REMA elevation, ice speed, shape +metrics, etc. CRS is Antarctic Polar Stereographic (PS_WGS84, lat_of_origin -71). + +Encoding — **positive-only two-class polygon segmentation** (label_type polygons; spec +sections 4 polygon-rasterize and 5 positive-only). We rasterize the polygons into 64x64 +(640 m) tiles at 10 m in a local UTM/UPS projection: + 0 = supraglacial_lake lake water surface (Feature_Cl == "Lake"). + 1 = supraglacial_channel supraglacial meltwater channel (Feature_Cl == "Channel"). + 255 = nodata / ignore every non-feature pixel (surrounding ice, firn, snow, rock, + unmapped area). + +This is a **positive-only foreground** dataset (two water-feature classes, no clean +background class): per spec section 5 we do NOT fabricate negatives — non-feature pixels are +left as nodata/ignore (255), and the pretraining-assembly step supplies negatives by +sampling other datasets. (This differs deliberately from the sibling Hi-MAG glacial-lake +dataset, which used a background=0 class; the orchestrator's dataset-specific directive for +this inventory is positive-only, and the surrounding Antarctic ice/firn/cloud is a less +clean negative than High-Mountain-Asia terrain.) Rasterization uses ``all_touched=True`` so +the smallest lakes (min ~96 m^2 ~= 1 px @10 m) and the thin channels stay visible at 10 m. + +Year: the inventory is a January-2017 (austral-summer melt-peak) snapshot. Supraglacial +lakes/channels are seasonal, so this is treated as a seasonal/annual label: a 1-year window +anchored on 2017 (spec section 5), ``change_time=null``. It is NOT a change label (a single +dated inventory, no pre/post pair). + +Tiling (mirrors the Hi-MAG glacial-lake dataset): each feature centroid is projected to its +local UTM/UPS zone at 10 m and snapped to a 64-px grid; the unique grid cells become +candidate tiles, and every lake/channel polygon intersecting a tile is rasterized into it. +Most features are small relative to a 640 m tile (median lake max-dim ~60 m; only ~3% of +lakes and ~14% of channels exceed 640 m), so a centroid tile captures the feature (large +features are captured as a representative central window). Selection is tiles-per-class +balanced (spec section 5), rarest class first, up to 1000 tiles per class, well under the +25k per-dataset cap.

Each date's polygon is the cumulative flow field, i.e. a +snapshot of the persistent fresh-flow surface present on that date. We keep all 14 dated +snapshots as separate temporal samples: the flow grows from ~4 ha (2016-05-24) to ~947 ha +(2017-05-31), so at a fixed location the label legitimately transitions background->lava +over the sequence, giving genuine multi-temporal signal. + +Change timing (spec §5): the mapping dates are precise (single calendar dates, <= ~1 month +apart), well inside the "known to within ~1-2 months" requirement, so we DO set a +per-sample ``change_time`` = the mapping date and emit two adjacent six-month windows split +exactly at it (via ``io.pre_post_time_ranges``): ``pre_time_range`` = the ~6 months +(<=183 days) immediately before the date and ``post_time_range`` = the ~6 months (<=183 days) +immediately after, with ``time_range`` = null. This lets pretraining pair the "before" image +stack with the "after" stack and probe on their difference; because the fresh basalt +persists, the cumulative mask also remains a valid presence mask after the date. (Caveat: +the mask is the extent AS OF the date, so imagery in the post window may show the flow having +grown a little beyond the mask near the active toe -- a minor, conservative under-count noted +in the summary.) + +Tiling: geometries are reprojected from EPSG:32605 metres into 10 m/pixel pixel space in +the SAME UTM zone (no CRS change; just a resolution scaling), then the flow's pixel bbox is +gridded into non-overlapping 64x64 windows.

Each polygon +carries a curated **GENERALIZED_LITH** field: a standardized generalized-lithology category +(33 distinct values), which is exactly the "generalized lithology categories" this dataset +advertises. We use GENERALIZED_LITH directly as the per-pixel class -- no CSV join needed. +(The geodatabase also carries geologic age via the Age table; a single-band per-pixel label +can only encode one attribute, and surface lithology is the more directly observable-at- +10-30 m property, so age is not used -- see summary.) + +Two of the 33 GENERALIZED_LITH values are not lithologies and are dropped: 'Unknown' +(26 polygons) and 'Dam' (7 polygons, an anthropogenic structure). The remaining **31 +classes** are kept (ids 0-30, assigned in descending global polygon frequency; see CLASSES), +including natural non-rock surface types 'Water' and 'Ice' (both observable at 10-30 m, +retained as legitimate surface units as in the GLiM sibling script). + +CAUTION (coarseness): SGMC is a compilation of state maps whose source scales are broadly +~1:500,000 -- a generalized product. Surface lithology influences terrain, soils and +vegetation and is partially inferable from S2/S1/Landsat at 10-30 m, but the map itself is +coarse and boundaries are approximate. Per spec 5 (large derived product) and mirroring the +GLiM approach, we therefore **sample bounded homogeneous tiles from large polygons** rather +than tracing polygon boundaries precisely: + + * We keep only polygons with equal-area footprint >= MIN_AREA_M2 (1 km^2, ~2.4x a 640 m + tile), large enough to (nearly) contain a tile. + * Each selected polygon seeds ONE 64x64 (640 m) tile in a local UTM projection at 10 + m/pixel, centered on the polygon's interior representative point (guaranteed inside the + polygon, even for L-shaped / multipart polygons). + * The seed polygon is rasterized into the tile with its class id; pixels OUTSIDE the seed + polygon are set to 255 (nodata / ignore), NOT a fabricated "background" class -- on a + geology map every land pixel is *some* rock type and we deliberately do not resolve the + neighbouring lithology at this coarse scale (positive-only foreground mask, spec 5). + Downstream assembly supplies negatives from other datasets. + * Candidates are dropped if the seed class covers < MIN_COVERAGE of the tile, so kept + tiles are genuinely homogeneous. + +Selection: class-balanced by the seed polygon's GENERALIZED_LITH (spec 5), up to +PER_CLASS=1000 tiles per class, under the 25,000 cap.

The canonical distribution +(https://eogdata.mines.edu/products/vnl/) now sits behind a Keycloak/SSO login gate for +which we have no credential (nothing in .env matches EOG, and the +authorized GEE service-account key referenced by TEST_GEE_SERVICE_ACCOUNT_CREDENTIALS is +absent on this host).

So we fall +back to BOUNDED dense_raster tiling of the WSF mask itself (spec 5, spec 4 dense_raster), +which is the intended fallback. + +Task: binary per-pixel classification, class ids + 0 non_settlement (source value 0) + 1 settlement (source value 255) +Both are meaningful classes (settlement vs non-settlement), so neither is nodata; nodata +(255) is only used for pixels with no source coverage (e.g. reproject fill at a tile edge). + +Sampling (spec 5, bounded regional): WSF is a global derived-product raster, so we download +only 34 representative 2x2 degree tiles -- major cities on every inhabited continent (diverse +settlement morphologies) plus rural / arid / boreal / forest tiles (clean non-settlement +landscapes) -- and cut 64x64 @ 10 m windows in local UTM (reprojected from EPSG:4326 with +NEAREST resampling, categorical). We build two window pools: + * settlement windows -- centred on settlement pixels, settlement fraction >= 5% (carry the + settlement footprint and its boundary; count toward class 1, and toward class 0 too when + they also contain non-settlement pixels, which nearly all do); + * non_settlement windows -- pure background (0% settlement), drawn across all tiles for a + clean, homogeneous, high-confidence negative-region label (count toward class 0 only). +Up to 1000 windows per class (spec 5), balanced, giving up to ~2000 samples.

Soil pH is a +quasi-static property (SoilGrids et al. routinely learn it from recent imagery over +legacy profiles), so per spec 5 (static labels) we anchor a single representative +Sentinel-era 1-year window (2020) on every point rather than the historical sample date. +This is the main caveat and is documented in the summary. + +The pH distribution is only moderately skewed but has long acidic/alkaline tails, so we +bucket-balance across the value range (spec 5) to give even coverage of the full pH range +when sampling down to the 5000-sample regression cap. + +Run: + python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.wosis_soil_profiles +""" + +import argparse + +import numpy as np +import pandas as pd + +from olmoearth_pretrain.open_set_segmentation_data import io, manifest +from olmoearth_pretrain.open_set_segmentation_data.sampling import ( + bucket_balance_regression, +) + +SLUG = "wosis_soil_profiles" +NAME = "WoSIS Soil Profiles" + +# ISRIC WoSIS 2023 snapshot (December 2023), extracted TSVs live under raw_dir. +SNAPSHOT_DIR = "wosis_202312/WoSIS_2023_December" +PROPERTY_TSV = "wosis_202312_phaq.tsv" # pH in water (pH-H2O) +DOWNLOAD_URL = "https://files.isric.org/public/wosis_snapshot/WoSIS_2023_December.zip" + +TOPSOIL_MAX_UPPER_DEPTH = 30 # cm; 0-30 cm topsoil convention +PH_MIN, PH_MAX = 2.0, 12.0 +GOOD_UNCERTAINTY = {"Circa 100 m", "100 m - 1 km"} +REPRESENTATIVE_YEAR = 2020 # Sentinel-2 era anchor for quasi-static soil labels +MAX_REGRESSION = 5000 +N_BUCKETS = 10 +SEED = 42 + + +def load_topsoil_ph() -> pd.DataFrame: + """Return one-topsoil-pH-per-profile records (quality filtered).""" + tsv = io.raw_dir(SLUG) / SNAPSHOT_DIR / PROPERTY_TSV + cols = [ + "profile_id", + "upper_depth", + "lower_depth", + "value_avg", + "longitude", + "latitude", + "positional_uncertainty", + "date", + ] + df = pd.read_csv(tsv.path, sep="\t", usecols=cols, low_memory=False) + df = df.dropna(subset=["value_avg", "longitude", "latitude", "upper_depth"]) + # Topsoil: shallowest layer with upper_depth < 30 cm, one per profile. + df = df[df["upper_depth"] < TOPSOIL_MAX_UPPER_DEPTH] + df = ( + df.sort_values(["profile_id", "upper_depth"]) + .groupby("profile_id", as_index=False) + .first() + ) + df["value_avg"] = df["value_avg"].astype(float) + df = df[(df["value_avg"] >= PH_MIN) & (df["value_avg"] <= PH_MAX)] + df = df[df["positional_uncertainty"].isin(GOOD_UNCERTAINTY)] + df = df[(df["longitude"].between(-180, 180)) & (df["latitude"].between(-90, 90))] + return df.reset_index(drop=True) + + +def main() -> None: + parser = argparse.ArgumentParser() + parser.add_argument("--max-samples", type=int, default=MAX_REGRESSION) + parser.add_argument("--n-buckets", type=int, default=N_BUCKETS) + args = parser.parse_args() + + io.check_disk() + manifest.write_registry_entry(SLUG, "in_progress") + + raw = io.raw_dir(SLUG) + raw.mkdir(parents=True, exist_ok=True) + with (raw / "SOURCE.txt").open("w") as f: + f.write( + "ISRIC WoSIS 2023 snapshot (December 2023).\n" + f"download: {DOWNLOAD_URL}\n" + "DOI: https://doi.org/10.17027/isric-wdcsoils-20231130\n" + "paper: https://doi.org/10.5194/essd-16-4735-2024\n" + "license: CC-BY-4.0\n" + f"regression target: topsoil pH in water, from {SNAPSHOT_DIR}/{PROPERTY_TSV}\n" + ) + + df = load_topsoil_ph() + print(f"{len(df)} quality-filtered topsoil pH profiles") + + recs = df.to_dict("records") + selected, edges = bucket_balance_regression( + recs, "value_avg", total=args.max_samples, n_buckets=args.n_buckets, seed=SEED + ) + print(f"selected {len(selected)} (bucket-balanced, {args.n_buckets} buckets)") + + tr = io.year_range(REPRESENTATIVE_YEAR) + points = [] + for i, r in enumerate(selected): + points.append( + { + "id": f"{i:06d}", + "lon": float(r["longitude"]), + "lat": float(r["latitude"]), + "label": float(r["value_avg"]), + "time_range": tr, + "change_time": None, + "source_id": f"profile_{int(r['profile_id'])}", + } + ) + io.write_points_table(SLUG, "regression", points) + + vals = np.array([p["label"] for p in points], dtype=float) + hist_counts, hist_edges = np.histogram(vals, bins=np.arange(2.0, 12.5, 1.0)) + io.write_dataset_metadata( + SLUG, + { + "dataset": SLUG, + "name": NAME, + "task_type": "regression", + "source": "ISRIC WoSIS 2023 snapshot (December 2023)", + "license": "CC-BY-4.0", + "provenance": { + "url": "https://www.isric.org/explore/wosis", + "have_locally": False, + "annotation_method": "field soil profiles + ISRIC standardisation", + }, + "sensors_relevant": ["sentinel2", "sentinel1", "landsat"], + "regression": { + "name": "soil_ph_h2o_topsoil", + "description": ( + "Topsoil pH measured in a water (H2O) suspension (WoSIS property " + "PHAQ): the negative log10 activity of H+ ions.

PANGAEA, https://doi.org/10.1594/PANGAEA.940078 (CC-BY-4.0); supplement to the +Circum-Arctic Map of the Yedoma Permafrost Domain (Strauss et al. 2021, Frontiers in Earth +Science, https://doi.org/10.3389/feart.2021.758360). + +Yedoma is a late-Pleistocene ice-rich (syngenetic) permafrost deposit. Its EXTENT is a +mapped geomorphic region compiled/harmonized from geological & stratigraphic maps -- like a +lithology/geology map, coarse but a valid per-pixel region class. We treat it as a +polygon -> dense region classification of Yedoma extent presence. It is NOT a dated change +event -> change_time=null, static 1-year Sentinel-era window. + +We use the ``IRYP_v2_yedoma_confidence`` shapefile: 13,833 Yedoma-deposit polygons in +EPSG:3571 (WGS84 North Pole LAEA Bering Sea, metres) carrying a ``confidence`` attribute +with three levels of Yedoma-presence certainty (confirmed / likely / uncertain), exactly +the class scheme named in the manifest. The confidence levels reflect mapping certainty of +the SAME phenomenon (Yedoma presence), not visually distinct land classes; a downstream +consumer training binary Yedoma presence should merge classes 1-3. We keep them separate +per spec 5 (do not drop classes; downstream can merge/filter). + +Class scheme (uint8): + 0 = background (non-Yedoma terrain inside a tile) + 1 = yedoma_confirmed + 2 = yedoma_likely + 3 = yedoma_uncertain + 255 = nodata/ignore (declared for consistency; unused) + +Each label is a 64x64 (640 m) tile at 10 m/pixel in the local UTM zone. Positive tiles are +area-weighted interior points of Yedoma polygons (per confidence class, so rare classes +reach their quota); every Yedoma polygon intersecting a tile is rasterized (all_touched) at +its confidence class value, the rest is background. Background-only negatives are drawn away +from any Yedoma so the background class has genuine negatives (the polygon boundaries are a +real land/region delineation, cf. peatmap). Tiles-per-class balanced to <=1000/class, +<=25,000 total. + +This is a large regional derived-product map; per spec 5 we draw a bounded, area-weighted +sample across the circum-Arctic distribution rather than exhaustive coverage. + +Run (idempotent): + python3 -m olmoearth_pretrain.open_set_segmentation_data.datasets.yedoma_permafrost_database_iryp_v2 +""" + +import argparse +import multiprocessing +import random +from collections import Counter +from typing import Any + +import numpy as np +import shapely +import tqdm +from pyogrio import read_dataframe +from rasterio.crs import CRS +from rslearn.const import WGS84_PROJECTION +from rslearn.utils.geometry import Projection, STGeometry +from rslearn.utils.mp import star_imap_unordered +from shapely import STRtree + +from olmoearth_pretrain.open_set_segmentation_data import io, sampling +from olmoearth_pretrain.open_set_segmentation_data.rasterize import ( + geom_to_pixels, + rasterize_shapes, +) + +SLUG = "yedoma_permafrost_database_iryp_v2" +NAME = "Yedoma Permafrost Database (IRYP v2)" + +# Source shapefile (extracted under raw_dir/extract) is in EPSG:3571, metres. +SHP = "extract/IRYP_v2_yedoma_confidence.shp" +SRC_CRS = CRS.from_epsg(3571) +SRC_PROJ = Projection(SRC_CRS, 1, 1) + +# Class scheme. +CID_BACKGROUND = 0 +CONF_TO_CID = {"confirmed": 1, "likely": 2, "uncertain": 3} +CLASSES = [ + { + "id": CID_BACKGROUND, + "name": "background", + "description": "Non-Yedoma terrain: any 10 m pixel outside a mapped Yedoma-deposit " + "polygon (other permafrost/land/water).", + }, + { + "id": 1, + "name": "yedoma_confirmed", + "description": "Late-Pleistocene ice-rich Yedoma permafrost deposit, presence " + "CONFIRMED from lithological/stratigraphic source-map information and field/expert " + "knowledge (IRYP v2 confidence class 'confirmed', conf_id 11-14).", + }, + { + "id": 2, + "name": "yedoma_likely", + "description": "Yedoma deposit, presence LIKELY per source maps (IRYP v2 confidence " + "class 'likely', conf_id 21-22).", + }, + { + "id": 3, + "name": "yedoma_uncertain", + "description": "Yedoma deposit, presence UNCERTAIN per source maps (IRYP v2 " + "confidence class 'uncertain', conf_id 31).", + }, +] + +PER_CLASS = 1000 # positive tiles per confidence class +N_NEGATIVES = 1000 # background-only negative tiles +TILE = 64 # 64x64 @ 10 m = 640 m tiles +REPRESENTATIVE_YEAR = ( + 2020 # static geomorphic label -> representative Sentinel-era year +) +QUERY_PAD_M = ( + 700.0 # padding (m, EPSG:3571) when clipping candidate geoms to a tile box +) +DEDUP_GRID_M = 1000.0 # spread positive centers on a ~1 km grid +SEED = 42 + + +# -------------------------------------------------------------------------------------- +# Loading source geometries. +# -------------------------------------------------------------------------------------- +def load_polys() -> tuple[np.ndarray, np.ndarray]: + """Load Yedoma polygons and their class ids.
