I am the author of the solution in Python for GRASS in the second link and we have a paper awaiting publication in Rend. Online Soc. Geol. It., "Tools for structural geology analysis in QGIS" (Alberti, Laloux and Zanieri), stereonets and rose diagrams (from the layer data), automatic cross sections, down-plunge cross section, etc (in Python). . For the representation of the boreholes in 3D, look at Is there QGIS plugin to allow 3d visualisation of geological borehole data similar to functionality of Target for ArcGIS? <http://gis.stackexchange.com/a/41719> with matplotlib <http://matplotlib.org/> or Mayavi <http://docs.enthought.com/mayavi/mayavi/>
Some geologists have also used the Qgis2threejs <https://github.com/minorua/Qgis2threejs> plugin -> Use Qgis2threejs plugin to create 3D visualisations of your stratigraphy data <http://hydrogeotools.blogspot.be/2015/01/use-qgis2threejs-plugin-to-create-3d.html> -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Geological-Map-Symbols-Continued-tp5248087p5248160.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: http://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: http://lists.osgeo.org/mailman/listinfo/qgis-user
