Hi all,
I tried to import an ArcGIS binary raster (corine land cover for the French
territory) with three fields on each pixels (VALUE, COUNT and CODE_06) using
the r.in.gdal command. The import works just fine, except that in the
resulting raster, in GRASS, I only get one field, which seems to be the
VALUE field (and not the CODE_06 field, which I am interested in, and which
is a categorical field, although coded with integers).
r.in.gdal will soon support import of category labels such as those
stored in the CODE_06 field. You can then inspect the labels with
r.category. GDAL supports reading and writing of raster attribute
tables, so far only the color rules stored in a raster attribute table
are imported, but I plan to add import of labels to r.in.gdal. Note
that this applies only to GRASS 7.

Good to hear that ;-). I will wait for the next release of r.in.gdal
(meanwhile I did import clc vector layers with v.in.ogr and later
managed the category labels with v.to.rast).
All the best, Manuel
Is there a way to produce a resulting raster with all the fields of the
initial ArcGIS layer, or alternatively to choose one unique field? Also, is
there a limitation on categorical fields. For instance, what if instead of
integer corine land cover codes I have literal labels, i.e. levels of my
categorical field coded with strings?
Cheers, Manuel
