New training section: 3D Geology diagram techniques

I’ve just added a new set of pages in the training section of this website. These tutorial pages cover 3D Geology diagram techniques. The first tutorials for 3D diagrams using a mixture of free and non-free software are live now. I will also make alternate versions of these tutorials that use only free software soon.

The page has written instructions and a series of screencasts that cover: georeferencing, digitising contacts, generating polygons and other steps. Links to other instructions that cover other parts of digitising a map are also included.

How to use https://koordinates.com/ to download/view spatial data

httpv://youtu.be/ykFjbOrf-Pc

https://koordinates.com/ is a website that allows users and data suppliers to upload/download data with a spatial component. The advantage this site has over other data repositories is that the user can choose which data they like, which format, and over which area in a granular way. It also has a very good interface for viewing data/metadata.
These sites are powered by koordinates.
