<p>Can you share the original DEM (before importing to GRASS) so we
can try on different systems?</p>

Carlos<br>
<br>
Not a silly question at all. I tried 'zoom to layer' with no
results.<br>
<br>
However, there is a mask for the vector map,
'analytical_area', which is<br>
much smaller the area covered by the DEM. The region is also
set to the<br>
analytical_area map and this might be the issue. Changing the
region to the<br>
raster DEM does not allow the map to display.<br>
<br>
While waiting for a solution to the display issue I tried
running r.flow on<br>
the DEM and aspact maps. Grass refused because of a region
resolution<br>
discrepancy between the analytical_area and DEM maps:<br>
<br>
DEM resolution: 3 3<br>
analytical_area resolution: 2.99763360 3.00134608<br>
<br>
'g.region vect=analytical_area res=3 -p' did not change the
floating point<br>
values to integer 3s.<br>
<br>
Thanks,<br>
<br>
Rich<br>
