Survex 1.2

Free
Survex is an open source cave-surveying application
 
1.2.6 (See all)

Survex is very powerful cave survey application, and is actively developing into a complete cave visualisation package. It has a sophisticated GUI frontend. It has no arbitrary limits, and so is particularly good for large complicated cave systems, or areas where you need to see the relationships between multiple cave systems.
