Thanks Michael,
I've imported lots of shapefiles by simply selecting the *.shp file
as the data source; does your method produce a different result (such
as transferring metadata, etc. to the GRASS directories)? I had
always understood that for the *.shp vectors, GRASS just needed the
*.shp file.
I'll try the *.hdr import with r.in.gdal as well; that would save a
step and eliminate the need for Arc on my system!

Hi Brandon,
A couple of additional pointers besides exporting as ASCII grids from
ArcGIS.
Using r.in.gdal, GRASS can directly read ArcInfo grid files. When
opening
them, select the *.HDR file as your data source. No need to export.
Similarly, v.in.ogr can directly read ArcGIS shape files. Select the
*directory* in which the shape files live as the data source (no
"/" on the
end); select the shape file (omit the ".shp" extension) as the data
layer.
Again, no need to export.
With both, depending on how they were made, you might have to
override the
projection info (or rather it's lack) in the ESRI file. But as long
as you
know that your ESRI file and GRASS location share the same projection,
that's OK.
