I have negative values in the drainage direction raster produced by r.watershed in the interior. Is this a bug? Or am I misunderstanding the definition of a sink? While looking into this, I also notice that I get different accumulation maps if I scale the elevation (e.g. divide by 100), even when using the "-s" flag. At first consideration, this does not make sense to me. > You can create flat areas (also with r.terraflow), then use the -b > flag of r.watershed to create a gentle slope for flat areas. I tried this and the accumulation map still has end-points (and direction has negative values) in the interior. -k. _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
