5 | | -A QGIS plugin for different Geovita custom processing algorithms. This plugin is currently under development, so new features may be expected! |
| 9 | +The Geovita processing provider for QGIS! |

9 | | -Status and Limitations |
10 | | -===== |
11 | | - |
12 | | -- Implemented [REMEDY GIS RiskTool](https://github.com/norwegian-geotechnical-institute/REMEDY_GIS_RiskTool) to run from QGIS processing |
13 | | - - It is important to read the manual for this project. Especially if you want to perform `vulnerability analysis`. This will require you to edit the polygon layers containing the `building` features (see specifications section below). |
14 | | - - Supported filetypes: `.shp` |
15 | | - - If you have an "in memory" layer or other fileformats you will need to save it to a `.shp` file. This is a restriction imposed by the underlaying submodule. |
16 | | - - Projection of layers: |
17 | | - - All layers `need the same projection` before you can run the algorithms |
18 | | - - The algorithm does not (yet) reproject layers. This means you have to do it manually first. |
19 | | - |
20 | | -Tools |
21 | | -===== |
22 | | -- **REMEDY GIS RiskTool** - These algorithms create a log directory in this location `%user%/Downloads/REMEDY`. For the moment this is hardcoded. |
23 | | - - `Begrens Skade - Excavation` The Begrens Skade - Excavation algorithm provides a comprehensive analysis of building settlements and risks associated with subsidence and inclination. |
24 | | - - `Begrens Skade - ImpactMap` The BegrensSkade ImpactMap alorithm calculates both short-term and long-term settlements that occur due to the establishment of a construction pit (this alg. takes a bit of time to run, open the log and refresh it to see the logged progress). |
25 | | - - `Begrens Skade - Tunnel` The BegrensSkade Tunnel alorithm provides a comprehensive analysis of building settlements and risks associated with subsidence and inclination due to tunnel excavation. |
| 11 | +**New algorithms are added to the provider as they are developed** |

27 | 13 | QGIS Plugin |
28 | 14 | =========== |
29 | 15 |
|
30 | | -This provider functions as a QGIS plugin (for QGIS >= 3.4) and is available via the standard QGIS plugins repository, so you can install it directly from within QGIS itself. |
| 16 | +This provider functions as a QGIS plugin (for QGIS >= 3.28) and is available via the standard QGIS plugins repository, so you can install it directly from within QGIS itself. |
31 | 17 |
|
32 | 18 | The plugin adds a new group to the Processing Toolbox for "Geovita", containing sub-groups with tools and algorithms to perform different tasks. |

36 | | -Specifications |
37 | | -============== |
38 | | - |
39 | | -It is crucial to understand the limitations of the [REMEDY GIS RiskTool](https://github.com/norwegian-geotechnical-institute/REMEDY_GIS_RiskTool) calculation methods. I would highly suggest reading the paper and the manual within the REMEDY repository. |
| 22 | +Check it out [here!](/geovita_processing_plugin/) |
40 | 23 |
|
41 | | -If you want to enable `vulnerability analysis` you will need some information on the buildings near the excavation/tunnel. You will need to add text fields to each feature in the building polygon layer for `Foundation`, `Structure` and `Condition`. See below for the allowed values! |
42 | | -- Class A is the best and D the worst. |
43 | | -- If i cell contains `-` it only means that this field only have 2 possible values. |
44 | | -- Copy/paste the values so they match! |

61 | | -## Results |
| 28 | +## Example results from the REMEDY GIS RiskTool |
62 | 29 | The following images show some example results. Both the excavation and the tunnel algorithm produces results for short and/or longterm settlements, but uses different calculation methods. The impact map calculates and illustrate total settlements in the impaced soil around the excavation. |
