I meant something like: r.watershed ele=elevation.10m@PERMANENT acc=elevation.10m.weight_acc flow=weight -f
madi, Well, that's different from the example, so I tried it: GRASS 6.5.svn :~/grassdata > r.watershed elev=dem10m.avg accum=dem10m.acc.weighted flow=weight -f --o SECTION 1a (of 4): Initiating Memory. SECTION 1b (of 4): Determining Offmap Flow. 100% SECTION 2: A * Search. 100% SECTION 3: Accumulating Surface Flow with MFD. 100% SECTION 4: Closing Maps. [Raster MASK present] followed by: GRASS 6.5.svn :~/grassdata > r.stream.extract elev=dem10m.avg accum=dem10m.acc.weighted thresh=1000 stream_rast=dem10m.lm.streams Load input maps and get start points... ERROR: Accumulation map does not match elevation map! [Raster MASK present] Still the same error generated. I'm quite puzzled. More suggestions certainly welcome! :-) Thanks, Rich _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
