Build 3D geological model from wells information

This plugin provides tools to create 3D geological models in QGIS.

Note

• The created layers are memory layers, the data are not saved, you should use the "save as" qgis function if you plan to store the layer as a shapefile or spatialite layer, you can also cpy/paste the layer feature in a postgis layer that has the right structure. This is intended to maximize flexibility of the source data format.

Quick dev install

You have to install the following dependencies:

• OpenGL for Python (python-opengl)
• QtOpenGL for Python (python-qt5-gl)
• shapely
• sphinx (python-sphinx)
• gitpython
• pytest, hypothesis and mock (for running tests only)

Clone the repo in a albion directory. Add the directory containing albion to your PYTHONPATH environment variable.

export PYTHONPATH=$PWD/..

Install plugin:

python -m albion.package -i

Run tests:

pytest

To generate a zip package without the documentation directory:

python -m albion.package -n
```


## Process

- Create project (no caps, no space, no accents in project name)
- Import data directory
- Create the grid (e.g. open an existing shapefile, select all features with Ctrl+a then copy/paste in the grid layer that has been switched to edition mode)
- Create a graph
- Set graph nodes (e.g. open formation attribute table, select feature by code, copy/paste into node layer and set the graph_id field of pasted features, use field calculator for that)
- Launch Auto Graph from the Albion menu
- Check graph, you can extend sections to interpolated either section by section of globaly with the Albion menu entry


## Interface

- Albion Menu:
    - new project (create db and load layers)
    - --
    - import data
    - compute mineralization (adds table and layer)
    - --
    - new graph (create table and views and new layers)
    - clean graph
    - --
    - export project (`pg_dump`)
    - import project (`pg_restore`)

- Albion Toolbar:
    - toggle section/top
    - current graph
    - grid line from points
    - select current section (either on top view, or orthogonal in section view)
    - previous section
    - next section
    - end distance
    - auto-connect
    - auto-wall and ceil

notes on 3D:
- togle visibility
- dynamic update on changes
