[GRASS-user] Stereo Photo-Metrology

[Benjamin Ducke]

Some further observations on using stereo:

I tried and work through the little tutorial here:

http://grass.itc.it/gdp/stereo-grass/

Loading images works fine.

Loading and restoring a Desktop works, although the main window
   size is not restored correctly and sub-windows are shuffled around

Loading the calibration file 'cal.txt' just crashes stereo.

I suppose the crash is somehow related to the compiler warnings
I reported previously.

Cheers,

Ben
