Re: [GRASS-user] [snap pour point for r.water.outlet]

I think you must use the accumulation map in the r.distance command. But bear in mind that you don't need the accumulation map but only your drainedge lines. Thus, you can threshold the flow accum map in order to delineate the rivers. And that could be a bit smaller than your complete flow

Re: [GRASS-user] [snap pour point for r.water.outlet]

Thanks Daniel, Since I am developing Grass Gis based interactive app to delineate watershed basin, I have to bundle those raster files along with other python packages. When the users installs the app, these files will be automatically copied and ready to use for "r.water.outlet" module through

Re: [GRASS-user] [snap pour point for r.water.outlet]

Hi Ang, I had replied off list. I'm now replying to the list so other can comment The idea is that to delineate watersheds, the outlet has to lie in a place with high accumulation. So if you get your outlet points a bit messed up, a way to force them to go to the right place is to use

Hi users, While using "r.water.outlet" to delineate watershed basin, although the coordinates of the stream was noted from google earth and fed into "r.water.outlet" module, it produces plain raster. Is there any solution to make sure that the coordinates of outlet point automatically snaps to
