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

The SexyTopo cave and underground surveying app for Android. Next-gen surveying with a sexy interface. It interfaces with a Disto-X and builds up a model of the cave. It provides a sketching environment for the cave surveyor to collect the details, and exports all the information to Therion, Survex, Compass, text (PocketTopo Therion) and SVG.

TopoDroid is an Android app for cave surveying, preferibly with a DistoX. Survey data are stored in a SQLite database, and can be exported in Compass, Survex, Therion, VisualTopo, Wall and several other formats.
Sketches are saved in a native binary format. They can be exported in Therion, cSurvey, SVG, DXF and PNG formats. The sketch canvas has a three-level grid, legs, splays, and stations to help drawing. TopoDroid uses cave iconic symbols (points), lines, and areas as in Therion.
TopoDroid can be used to calibrate a DistoX.
For more detail, refer to the TopoDroid page
Simple application significantly speeds up the surveying process by automatically downloading DistoX, DistoX BLE, BRIC5, Shetland Attack Pony or CaveSniper measurements. In addition, it provides a built-in image editor for sketching plans and sections.

The Cave Converter tool converts between various cave survey file formats. Primarily to enable users of DistoX devices to get their existing data into PocketTopo, and their new survey data out of PocketTopo and into Survex format.

Some minor bug fixes in this January 2013 release:
Bug reports and requests to support other formats always welcomed.
Create therion templates for scanned survey notes, decreasing the amount of time necessary for doing the mundane job of creating plan, profile, and cross-section scraps for each scanned page of survey.
This script relies on imagemagick's display program, so as long as you have display and can run shell scripts, the script should run. I've only used/tested it on Fedora, but I imagine it will run on a mac without difficulty. It's possible you could get it to run in windows if you have a decent shell available.
The script is far from perfect and still has plenty of rough edges, so feel free to comment and suggest changes if you feel compelled to.

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 and it is easy to interrogate survey and map elements, but many of Loch's features are not supported/exported yet.
You can export both maps and models from Therion in .3d format. The 'map' outputs provide a nice quick way of visualising scraps and scrap names in a 3d viewer, whereas the 'model' outputs produce a wire-frame.
A PHP class framework for therion file structures. Originally created to export data in therion format from the Austrian SPELIX cave data system.
Some days ago I released the second public release (0.2.0) with basic centreline and survey support and (I think) all important structures present (however not all of them do something right now, thus the alpha state). The rabbit example is parsable and writable again with core features (like centreline).
TopoLinux is a suite of caving programs including;
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 PocketTopo files (surveys and drawings).
TopParser provides an alternative method of converting PocketTopo files to Therion Files.
TopParser takes a PocketTopo *.top binary file and produces a set of Therion text files to represent;
The Therion files can be automatically named and inserted into your existing survey dataset.
Produce a surface mesh to be able to take mesurements between surface and cave.
therionsurface2survex takes a therion source file containing a surface mesh (`surface … grid … endsurface`) and converts it into a survex .swx file. This can be compiled by `cavern` into a survex .3d file, which may be combined with your cave's 3d-file. This allows for example to take distance measurements between cave tunnels and the surface.
Since Version 1.0, the program supports also GDAL ASCII grid files as input and therion centerline format as output. This allows to directly parse ASCII height data into a surface mesh directly usable by therion.
It translates data from Compass format (*.dat) to the format used by Therion (*.th).
It translates data from Survex format (*.svx) to the format used by Therion (*.th).
Written for the data set I was managing, not a comprehensive converter, hopefully it will be a useful starting point for other people wishing to convert from Survex format to Therion.
To use run this script in your root directory of the data set.
Therion editor did (still can?) leave empty lines or areas, that have been reported to cause problems. This command line pipe removes these
This script was written for a specific data set. It has not been tested beyond, it is placed here as a starting point for others. Warning, this script modifies files without confirmation, backing up data before use is strongly recommended.
grep -rnIH -A 1 "^area " * |grep endarea|tac|awk -F- '{system("sed -i " $2-1 "," $2 "d '''" $1 "'''")}'
The above works for areas, substitute line and endline to also do areas. It is strongly recommended that the pipe is built up one step at a time to check it works on the data set. Below is an explanation of each step with known problems indicated.
grep -rnIH -A 1 "^area " *
Lists all lines in files with the 'area' as first word followed by a space plus the next line. If your files are indented this may not work, the ^ can be removed, but if the endarea has a space after, this with break the rest.
grep endarea
From the above list only the lines that contain endarea
tac
Reverses the order. When the lines area removed it is done by line number, so have to go from the end of the file otherwise susequent lines will have changed number.
awk -F- '{system("sed -i " $2-1 "," $2 "d '''" $1 "'''")}'
Deletes the lines, the -i just does it, removing the -i dumps it to screen, without changing the file
