Archival copies of cave related software that has been used in NZ are stored in the NZSS Repository/Survey Resources/Applications folder.
eg Bazaar Compass OnStation PocketTopo RosettaStal TerrainTool Therion SMAPS Survex
In the first instance you should however seek a current version of the software from the authors 'official' source.
Why store our own copies?
A lot of applications prove not to be very backwards compatible, or eventually disappear in a puff of apathy. If you have a significant amount of source data and want to maximise the chances it can be used in the future, ask for a copy of the install files to be placed in the NZSS Repository.
