I am sorry for reopening this thread, but I would like to fix this issue and I have a question.
We have some passages, that were surveyed extremly precisely using laser theodolite and station coordinates were calculated in its own software. We usually import them using fixes and data no-survey and want these shots to be added to total survey length. Do you have an idea, how to treat this situation and to stay compatible with survex? S.
