To delineate basins the water outlet must by on top of a lino of high acumulation (river) as is explained in the Notes section in r.water.outlet manual [1]. A trick I saw being used was to user r.distance (or v.distance) prior to r.water.outlet. I had a map with the outlet of 100 basin but they were not in the right place. So I used r.distance to find the nearest river cell close to each outlet and then use r.water.outlet. For those comming from ESRI backgound, this is the equivalent of the "snap pour point command".
Daniel, I have an upcoming project where using r.distance to find the appropriate cell for r.water.outlet may be quite useful. Thanks, Rich _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
