[Francophone] QGIS et géologie

[gene]

J'ai oublié de poster le résumé de l'article

"QGIS is a free and open source GIS software that is highly customizable
through the use of Python scripts. We examine the available tools for
structural geology analysis. The common basis of all these tools is
constituted by scientific and also visualization modules, like NumPy, SciPy
and Matplotlib. A few structural geology Python modules exist, the most
notable being Apsg by Ondrej Lexa. It allows manipulating orientation data
and presents convenience functions for plotting them in Matplotlib
stereonets. Based on these scientific, geologic and visualization modules it
is possible to produce scripts or processing plugins for cross- section
preparation, attitude interpolations on regular grids and stereonet
plotting. Plugins based on Qt GUI are just a few, devoted to the analysis of
the relations between geological plane traces and topographic surfaces
(qgSurf plugin), to the preparation of cross-sections with projection of
geological attitudes and intersection of geological traces or polygons
(qProf plugin), management of hydrological data (Midvatten plugin) or
digitalization of fractures and other lineaments from referenced digital
photos (digiFract plugin)."
