Good evening,
I'm looking for some way of accessing/using the raster attribute table of some data I have ... unfortunately I suspect it is from Arc. Searching on-line I haven't found anything that points me to GRASS tools to import/read raster attribute tables... Is it supported?
Here's a sample list of the files I have:

Otherwise you could import the raster map and then the attribute table with db.in.ogr.
From the table you could then build reclass rules for r.reclass.
(Not tested)
Cheers

Thank you for the tip Stefan - most appreciated! I'll give that a try and report back.

yes, r.in.gdal can dump raster attribute tables as csv files. Moreover, information in raster attribute tables is automatically imported as long as the field definitions contain information about how to use a field, e.g. for color information or for labels.
Otherwise you could import the raster map and then the attribute table with db.in.ogr.
I don’t think db.in.ogr can read raster attribute tables: raster attribute tables are not equivalent to vector attribute tables.

BTW: I have added that to the manual page of r.in.gdal.
