Thanks for your message. If I understand correctly, you use the text export
from PocketTopo (the therion export?) and convert that to survex shots. This
is obviously pretty trivial, and I have written a 10 line python code doing
exactly that.

I am more interested to read the *.top files (the original PocketTopo files)
directly. Do you have code for that? Or at least a description of that binary
format? The *.top format seems to be somewhat more convoluted than most binary
formats, so it is not even easy to guess how to access that data.

Thanks, Martin
