Hm, can i display the coordinates of entrances somewhere in loch? survex
shows the coordinates of the stations / mouse pointer.
Maybe the dataset i have received is not georeferenced at all; i just
guessed it because i see coordinates on rendered therion maps of the caves,
but of course this could also be just an arbitary string in the compiler
file.

" the last problem now is, that the surface lox is in a different
coordinate system than the caves (EPSG:31468 vs. lat-long) :/ I hoped loch
would recognize this and recalculate as appropriate, but that was not the
case. Is there some option to convert conveniently?"
I have never used Lat/Long but I do have a quite extensive data set that
uses two different EPSG numbers, one UTM - and I think there's an IOS or two
in there somewhere but cannot find them quickly - and this has generated a
lox file that seems to have put everything in the right places. I have only
ever seen "computer says no" messages when there have been sections where
the co-ordinate system had not been specified at all.
I'd be wary about stating the cs in your thconfig file as that will clash
if a different cs has been used elsewhere in the data set, I think.
