Updated by: bjoern (2007-10-21 16:18:43)
New upstream release.
Therion aids the process of drawing up cave surveys (maps). Drawings are done over scans and can be distorted to fit the centreline data. Output is in single plan or atlas style in PDF files. All data is stored in text files and a Tcl/Tk map editor (xtherion) is provided to aid in the creation of the files. It is compatible with Survex and uses it for the centreline processing. TeX and metapost are used to generate the images.
