+ This notebook demonstrates how to
+
+ 1. Read in Ground Investigation (GI) data from [GEF files](https://bedrock.engineer/reference/formats/gef/gef/) using the [pygef](https://cemsbv.github.io/pygef/) library.
+ 1. Use [`bedrock-ge`](https://github.com/bedrock-engineer/bedrock-ge) to convert that data into a standardized GI database.
+ 1. Transform the GI data into 3D spatial features with proper coordinates and geometry ([OGC Simple Feature](https://en.wikipedia.org/wiki/Simple_Features))
+ 1. Explore and analyze the GI data using interactive filtering with Pandas DataFrames and interactive visualization on a map using GeoPandas.
+ 1. Export the processed GI database to a GeoPackage file for use in GIS software, like QGIS or ArcGIS.
+
+ + [Geotechnical Exchange Format](http://localhost:4321/reference/formats/gef/gef/) (GEF) is a standardized, + text-based format designed to facilitate the reliable exchange and archiving + of geotechnical investigation data, particularly CPT results, across + different organizations and software platforms. GEF can also be used for + other types of soil tests, like CPTs. It is widely used in the + Netherlands and Belgium in ground investigation. +
++ A DataFrame is like a spreadsheet, it is a two-dimensional data structure that holds data like a table with rows and columns. +
