Thanks for responding.
I think I was a little unclear in my original description. My
xy-location raster is stored as pixel values (720 rows and 1440
columns, with the origin (0, 0) at the bottom left corner),
such that an individual pixel might have a coordinate of 125, 256.
I need to somehow "project" this xy location raster into a lat long
location where
well, r.in.gdal might do the trick.
it can even create a new location with the parameters specified in the
HDF header.
try gdalinfo to see if there's any projection info, then r.in.gdal
in=HDF_file out=rastername location=HDF_location

This is what the georectifier is for.
