Re: [GRASS-user] Stereo Photo-Metrology

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

[GRASS-user] r.terraflow

Hi list. I'm trying to use terraflow for the very first time, because r.watershed is too much time consuming for my dataset. I've updated it to include the recent patches to categories coding. In the new coding scheme, when using the sdf option, 9 directions are depicted (0,1,2,4,8,16,32,64,128).

Thanks Luca. The coding mapping seems correct. So, zeroes are for unsolved pixels... I'll do some tests to compare the results with r.watershed. At now they seem quite different. I'm not sure if I should trust onflow directions from r.terraflow to use them in r.water.outlet... 2008/7/28 doktoreas
