[GRASS-user] r.watershed - forgot to mask out no data?

[Daniel Victoria]

Hi,

After a couple of days I got a successful output from r.watershed.
Well, almost successful. Some basins looks very weird, as you can see
in the attached file. Is it because I did not mask out the null cells
on the dem map (white area on dem30.jpg)?

Thanks
Daniel
