If I understand that correctly, PocketTopo is still completely closed and the file format not documented. Also from reading your comments, the PDA software seems to be quite inflexible (first splay shots, then next target). Since I am also considering going that route, these seem to be severe limitations. Working together with people using PocketTopo, it is quite inconvenint not to have true Therion *.th files with the full set of measurements, but just processed data. It would be great to be able to write a *.top conversion utility, but for that the file format needs to known. Best, Martin

Loch: maximum resolution of image?
by Wolfgang Zillig 30 Apr '10

30 Apr '10

Hi, I once read somewhere that the overlay size is limited. Can anyone tell me where this limit is and where it could be changed (is it hard coded or hidden in a ini-file)? Is there something similar for the elevation model? Many thanks Wolfgang

DistoX and PocketTopo with Therion
by Bruce Mutton 13 Apr '10

13 Apr '10

Hi there I have a Disto arriving hopefully in a few days, and looking ahead I've been tentatively trialling PocketTopo on my PC. I suspect therein lies my first problem. Perhaps it only has limited functionality on PC's? I can manually enter data, but I can not seem to draw passage outline. The Export Therion format does not seem to produce data in a format similar to what Therion normally accepts - after the data it produces some form of co-ords separated into plan and elevation partitions. Most of the survey stations are converted to 10 digit numbers and all of the keywords are in capitals. Much of the file content could be made Therion compatible relatively easily using a text editor, but surely this is not what is intended? Obviously there is something significant here that I am missing. Have searched about but have not found the solution yet. Does anyone have a small dataset that demonstrates the interaction between PocketTopo and Therion? Bruce
