I am trying to use r.water.outlet to calculate the corresponding
watershed to a given outlet-point. As input map I use the resulting
drainage-map derived from r.watershed.
The resulting watershed is always one pixel large, exactly this pixel I
gave the input-coordinates for.
Does anybody had success to calculate more-or-less accurate watersheds
with this module?
I tried in spearfish w/ grass 6.2.1.
r.watershed elev=elevation.dem acc=acc drain=drain basin=basin
r.water.outlet --o drainage=drain basin=result_outlet
Thanks for any hints.
