Another alternative, if you just want to use the GRASS raster files in
ArcView and don't have access to ArcInfo, is to uncompress the GRASS cell
file and bring it into ArcView as a .bil format. This works fine for 8-bit
raster files (category values 0-255). You can also build a .hdr file with
georeferencing info with a text editor. I can send you a sample if you like.
It's one that came with some SPOT imagery. I just edited that .hdr file and
changed the rows, columns, cell size and coordinate of the upper left corner.
