I have not tried this with plt but with 3d, however according to the thbook it should work. import file.plt calibrate [<x> <y> <z> <X> <Y> <Z>] Where coordinates in the imported file are shifted from lower-case coordinates to upper-case coordinates. I hope I have understood what you are trying to achieve, if not a sample file might help Andrew On 03/08/12 19:20, Jonny Prouty wrote:
Hello all,
I have a compass PLT file that I would like to import into an existing therion project that I have. The therion project has numerous fixed stations, all in the same UTM zone. Unfortunately, if I try to equate a station in the PLT file with the equivalent station in my project, I can't proceed as I can't mix local (in the PLT file) and global (in my project) coordinate systems. If I comment out all of the "cs" commands in my therion project as a test, I can't proceed because therion won't allow two fixed stations to be equated with one another. Removing the "cs" commands isn't really a viable option anyways since I need the stations to have real-world coordinates so that I can load the maps into QGIS and GRASS.
My question then is is it possible to override the coordinates of an imported PLT file, transforming them into the coordinate system of my project? Thanks very much in advance!
Best regards,
Jonny
