Cross-section maps vs. profiles

 

The new pygsf release (v. 6.1.0) makes it possible to create and visualize directly in Jupyter, just using Python, topographic maps with superposed traces of parallel profiles, numbered by their ids as in the example below.

These map traces can be compared with the topographic vertical profiles displaying also geological information, for instance geological outcrops, that can be composed into an animation.

 

Next step would be to implement  the creation of animation with both the topographic vertical profile and a map with the corresponding map profile trace, so to make easier to relate each vertical profile with the related map trace.

The map traces and animation creations are detailed in this Jupyter notebook:

Cross-section intersections of line and polygon layers with qProf in QGis

A new release of qProf, plugin for QGis, allows to determine the intersections of line and polygon layers, representing for instance faults and geological outcrops, on a vertical cross-section.
These new functionalities complement those already available for projecting geological attitudes and lines on a cross-section.
The resulting data can be saved as shapefiles and csv.

Example of cross-section representing geological polygon layer intersections with a topographic profile.

The plugin can be installed/updated via the plugin manager of QGis. Alternatively it can be downloaded from the QGis plugin repository:
http://plugins.qgis.org/plugins/qProf/
or from the Bitbucket repository:
