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-qt4-gl)
• shapely
• 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

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 cpy/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, cpy/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
