That's not enough, the current computational region must be aligned to
the dem, otherwise you might have the same resolution, but the
computational g

Thanks Markus,
Let me make sure I understand. For best results I need to set the resolution
to 10m for the 1/3 arcsec. With the region set as it is (most of Northern New
England) when I do this I run out of memory. To over come this, I can set the
region to just encompass just the NED13_01 s

Apparently, the dem has a resolution of 1/3 arcsec (~10m), maybe
reprojected and resampled. With these extends, there would be about
186 million ce

Problem was the resolution it starts working when I set it to 100m. The dem is
~69 x 27 km.
Thanks

Any idea what I'm doing wrong?
Kurt,
Look at the amount of memory your file wants to be allocated: several
Petabytes. H
Hi all,
I am trying to run r.watershed using a dem I converted from a USGS Seamless
server 1/3 arc map.
This is what I get:

max.slope.length=10 accumulation=acc13_01 drainage=drain13_01 basin=basin13_01
