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

[manuel.martin]

Hi Ben,
Thanks for the reply. I tried with the band option but it looks like 
gdal does not detect the multiple fields as multiple bands :

GRASS 7.0.svn (lambert93):~ > r.in.gdal --o \
 > 
input=/home/manuel/Desktop/sftp/Projets/Projets/Zones-humides/base_sig/dsm_data/clc/clc06_250m 
\
 > band=3 output=testclc
WARNING: Raster map <testclc> already exists and will be overwritten
WARNING: Datum <Not_specified_based_on_GRS_1980_ellipsoid> not recognised
          by GRASS and no parameters found
Projection of input dataset and current location appear to match
ERROR 5: 
/home/manuel/Desktop/sftp/Projets/Projets/Zones-humides/base_sig/dsm_data/clc/clc06_250m: 
GDALDataset::GetRasterBand(3) - Illegal band #

ERROR: Selected band (3) does not exist


Cheers, Manuel
