Complementary Cave Processing Applications

Survex

If installed on a machine running therion, then by default 'survex' survey processing is used, which may yeild a survey network shape slightly different to the 'therion' network due to differences in loop closures. It also echos some additional useful information to the therion.log file

It's viewer Aven is an alternative to Therions Loch. The .3d files are very fast to export, and Aven is quite refined, but many of Loch's features are not supported/exported yet.

PocketTopo

A nice little application that, once you've obtained a cave proof PDA and DistoX, allows you to do away with the simple, foolproof, pencil and paper - compass clino tape, and rely instead on batteries and the vagaries of recalcitrant hardware and software.

Follow the links on these pages to find out more.

Once successfully used, it's hard to go back.

QTopo

QTopoShot (QTshot) is part of the QTopo programs for the DistoX. It is designed as DistoX-frontend to Therion, and handles a single survey at a time. With QTshot one gets the centerline data from the DistoX, and draws the scraps. Survey data are saved in a custom format (plain text), and can be exported in Therion format as a .th file. Scraps are saved in Therion format as .th2 files.

QTshot can export the survey data also in Survex, Compass, and PocketTopo format. Import of PocketTopo files (surveys and drawings) is under progress.

QTshot is part of the TopoLinux program suite and can be found on googlecode. Based on QT. Developed only for Linux, but should be portable to Windows (tested) and Mac OS X (not tested).
