I have had problems with this command if I am not working in areas ST or SN. (Mendip , west part of South Wales.)

 

using cs OSGB:SO      # (east part of South Wales)

 

I get error ;-

 

therion 5.3.9

initialization file: C:\Program Files (x86)\Therion/therion.ini

configuration file: thconfig

C:\Program Files (x86)\Therion\therion.exe: error -- gelynnen.th [10] -- unknown coordinate system -- OSGB:SO

writing xtherion file ... done

 

It runs 100km out if changed to cs OSGBT  (read  ST)

or correctly positioned if using  cs EPSG:27700 -calibrate [0 0 0 300000 200000 0]

 

other 100km grids not working but checked, SV SU SS SM SO SP  (SD SE NY NZ - Dales)

 

Cheers
