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.
Aligning and adjusting images using photoshop: Core scan example
1 About this approach
In this approach we use photoshop to align images and make image brightness, contrast and other adjustments. These instructions are written for photoshop CS6, but they should be applicable to other recent versions of Photoshop.
This approach has these advantages over aligning images in adobe illustrator or other vector package:
- Opportunity to automatically align images
- Ability to make image brightness, contrast and other adjustments live (and reversibly)
- Ability to make granular image adjustments (i.e. at the edges of aligned images to make them match better).
Digitising a geological map in ArcGIS Desktop
I’ve made a new page on the website which covers digitising a geological map in ArcGIS desktop. 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.
