Hi all,
first of all thanks a lot for your help!
Unfortunately I couldn`t solve my problem yet. I have been trying several ways:
1) I made sure that my pour points have been set (manually) on the flowacc layer and all extents and projections are well chosen, then I entered the pour points and the flowdirection files into the watershed tool. --> Result: tiny watersheds
2) I created a few pour points manually and then applied the snap pour points tool on them. --> Result: the snapped pour points appear displaced (each around 8x2 pixels into the same direction) from the old points I set manually. (I am attaching a screenshot).
3) The same thing happens when I convert points to raster. The newly created raster cell always remains displaced from the original point.
I am working with the Magna_Colombia_Bogota projection only and have made sure that it has been set correctly in the Environment options.
Do you see any possible error?
Cheers,
Carina
