Hi all,
i have a problem using Grass 6.5 with a raster elevation map running the
command 'r.terraflow'.
I need to obtain the flow accumulation with MFD.
The error is the following:
'cell file dem resolution differs from current region'.
I ran the command 'g.region -ap rast=dem' and this is the result:
projection: 1 (UTM)
zone: 33
datum: wgs84
ellipsoid: wgs84

south: 6541497.53951495
west: 500200.31922317

nsres: 10
ewres: 10
rows: 10959
cols: 14931
cells: 163628829
with 'r.info' the result is:

Please can you help me? Any idea about what's wrong?
Sorry if my question is trivial.
