Just when I have gotten used the process of importing USGS DLG files
to GRASS vector, I have a monkey wrench tossed into my machinery...
now I have some other format to deal with (for what I am guessing is land
cover data; a raster representation perhaps.)
So I call upon the collective expertise of this mailing list again
to help me out of the fog. Hopefully to someone this is a recognizable
situation. Below is the top 10 lines of one of the files. Can you tell
what it is? If so, how do I import to GRASS?

This is GIRAS vector data. I just got a diskfull of the stuff myself,
and havn't figured out how to process it. I do have documentation
about it, and the somewhat arcane details of the file format. (Chris, I
can fax you the relevant pages if you want.) If someone knows about a
GIRAS-to-anything, please let the list know.
There is a GIRASARC command in arcinfo, which I may wind up doing, and then
ungenerating to get to GRASS, but (a) not everyone around has arcinfo (ahem),
and (b) that's cheating.
