add the stations and entrances altitude as a new column in the attribute table,
cut the lines and areas shapefiles to keep only what is inside the outline (expect for the option clip off); Before running this script, I often need to test the validity of the polygons shapefiles to make sure that they are valid…

We also make some svg symbols corresponding to symbols used by Therion, but this is not yet complete. (If someone has already a svg symbols library for therion shp, I am interested !)

For those interested, this is now partially included in the Samoëns cave repository : https://github.com/robertxa/Topographies-Samoens_Folly (written mostly in French)

To make the GIS files, I run the « SamoensGIS.thconfig ». After compiling Therion files, it calls Python scripts (edit the .thconfig to check if the lines are not commented) that are in Samoens-GIS/Scripts (https://github.com/robertxa/Topographies-Samoens_Folly/tree/master/Samoens-GIS/Scripts). The whole QGIS project is not uploaded on GitHub as some files are to big for Github. But I can share it on demand.

For now, this is still a bit dirty (and still dedicated to this project, you will need numerous changes to apply it to an other project), I am still working on this. If you try it, if you miss a specific file, if you have any questions or suggestions/improvements, etc. do not hesitate to contact me !

A question has come up from one of my caver friends who is very new to cave survey but an old hand at ArcGIS and various other ESRI tools. He earns a living as a GIS expert.

He would like to get a georeferenced TIFF (GeoTIFF) which includes GPS coordinates of survey stations. I looked at the KML file produced by Therion and find no references to survey stations. A KML file is really just a long (very long!) list of GPS coordinates, so it probably could include survey stations.

So my question for the group: Is there a way to produce a GeoTIFF file which includes survey stations?

Related question: Do the ESRI outputs from Therion include survey stations?

Thanks!
