[GRASS-user] r.in.gdal for importing categorical ArcGIS binary rasters

[manuel.martin]

Hi, I just compiled grass r59073 and gave a try.
I could not get the attributes imported along with the raster, but maybe 
am I missing something from the new revision of r.in.gdal (although from 
the code it looks that the import of values from the attribute table 
should be automatic?).
Markus, I just sent you the ESRI layer I am trying to import, in case 
you would like to try as well.

Thank you in advance

Manuel
