 <em>r.in.aster</em> rectifies, georeferences, and imports Terra-ASTER imagery
 to current location using gdalwarp, hdf 4, and r.in.gdal, using projection parameters
-from g.proj. It can import Level 1A, Level 1B, and relative DEM products.

   the <b>type</b> of processing used, the image <b>band</b> to import, and an
