Survex is free and open-source cave surveying software, licensed under the GNU GPL. It is designed to be portable and can be run on a variety of platforms, including Microsoft Windows, Mac OS X, and Unix-like. Survex is very powerful cave survey software, and is actively developing into a complete cave visualization package. Centreline data is entered using plain text files, which are processed by 'Cavern'. The text files contain a hierarchy of cave surveys, each of which consists of a list of survey legs, which join survey stations. This program calculates the real world coordinates of survey stations, taking into account loop closure errors using least-squares minimization. This processed data can then be visualised using a GUI front end called Aven. Survex 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. More information...
