Dear list members,

I am currently working on the generation of watersheds for a small european
Due to the amount of data (4089x2860, res=20) I have to use r.terraflow
instead of r.watershed.
In my opinion the outcoming watersheds of r.terraflow are not really
compact, rather fuzzy at the borders. See attached file.
Could that be the problem for my results in r.thin, which are completly
unuseable? See attached file.

Whats going here?
Any ideas to solve this problem?
