Geological compass for QField

Show and tell
1

Hi all. Thanks to help by @Mathieu_Pellerin , @cuprico and @fggs-pascal , I’m quite happy to offer my suite of geological field mapping tools for QField:

  1. A geological compass, long wished by fellow (structural) geologists; it is based on the original code by Mark Jessell (GitHub - swaxi/compass: compass plugin for QFIELD · GitHub) with, I hope, some improvements :
    GitHub - jfmoyen/QField_qml_Geological_compass: A QField plugin adding a geological compass app to record plane and line orientation · GitHub

On the github page, you will also find a page describing the inner workings of the plugin, for fellow developers.

  1. A small modification of Snap! (GitHub - opengisch/qfield-snap: Allow for snapping of photos to create a feature at the current device location. · GitHub), simply by sending the new photo to a pre-defined layer (rather than the active one): GitHub - jfmoyen/QField_MySnap: The snap! plugin, slightly modified · GitHub

  2. A database, and QGS project template (GitHub - jfmoyen/QField_Geological_mapping_template: A QGIS template project for geological mapping using QField · GitHub), to store the data collected.

It seems to work on my device (I will try more next week, I’ll be in the field). Now bracing for the unavoidable bug reports… :face_holding_back_tears:

PS. I take the opportunity to mention the beautiful QGIS work by the SWAXI group (Mark and friends): SWAXI · GitHub. They have a superb suite of QGIS plugins to plot stereonets, work with potential (gravi and mag) fields, etc.

Also the cool qgSurf (qgSurf — QGIS Python Plugins Repository) by Mauro Alberti, to calculate the trace of geological planes on DEM or calculate the attitude of a plane based on observed points.

Lastly, the French BRGM is releasing their 3D geological modeller (ForGEO — QGIS Python Plugins Repository), an evolution of their historic tools (GDM and GeoModeller). User-friendly is not the term that comes to mind, but it seems extremely powerful!

So we can really do a lot of geology in QGIS/QField these days :slight_smile:
