How to make a geological map with QGIS – Tutorial

Hydrate

A good spatial representation of the geological features requires not only high quality field data but also the right symbology and graphical resources. We can define QGIS as the tool that can create awesome geologic maps but still some resources have to be developed for a massive use. We have explored some QGIS tools related to the representation of geological units and developed symbology to represent geological contacts, faults and other geological features.

This tutorial deals with the representation of geological information at regional scale from the Central Beaverhead Mountains, Idaho, US and creates a geological map through a series of processing and representation steps as:

  • Applying styles to geological units

  • Representation of contacts and normal / thrust faults

  • Representation of inclined beddings

  • Representation of anticlines / synclines

  • Map composition with legend, scale bar, grid and external graphs

The tutorial is based on a webinar given on April 27, 2021
