[GRASS-user] importing a adf file - resolution question

[Kirk Wythers]

I just used r.in.gdal to import a .adf. The files came from the global aridity and pet database hosted by CGIAR CSI

http://www.cgiar-csi.org/data/global-aridity-and-pet-database

Originally I was getting the warning:
WARNING: G_set_window(): Illegal latitude for North

so I used the -l option. The file appears to have imported

GRASS 6.4.3 (globe_30s):~ > r.in.gdal -l in=~/projects/global_aridity/AI_annual/ai_yr/w001001.adf out=ai
WARNING: Map bounds have been constrained to geographic coordinates. You
         will almost certainly want to check map bounds and resolution with
         r.info and reset them with r.region before going any further.
Projection of input dataset and current location appear to match
 100%
r.in.gdal complete. Raster map <ai> created.

I am trying to check the layer with r.info and I see that the resolution looks odd (N looks correct, should be 30 second, but E looks weird):

GRASS 6.4.3 (globe_30s):~ > r.info ai

I'm not sure what to do with this? Any suggestions would be most appreciated!
