Therion 5.3.8 (beta) released

Therion is a complete package which processes survey data and generates maps or 3D models of caves.

A new beta version (5.3.8) has been released and is available here.

Therion solves the most annoying problem of cave cartography – how to keep a map of large and complicated cave system always up-to-date. 

Main features include:

Complete maps with all the detail. No additional ink stroke is needed.

• Maps are dynamic, always up-to-date – i.e. they are automatically re-drawn after loop closure, blunder fix, scale or symbol set change
• 3D models are created using 2D maps

It runs on wide variety of platforms: Linux, Windows, Mac OS X. It is completely free, released under the terms of GNU GPL, with source code available. It doesn't require any other commercial software to run.
