Hi all.
I tried this command, but I always get a map full of 0. I start from
a drainage map from r.watershed, as described. Anyone confirms, or am
I doing something wrong?
All the best.
I guess you mean r.water.outlet?
You probably know already, but maybe it's worth repeating:
1- The input must be the drainage *direction* map from r.watershed.
2- And it's crucial that the easting and northing parameters for the
outlet point lay exactly on a stream. Zoom in very close to the
streams raster at the outlet point and check for the exact coordinates.
