DESCRIPTION               = "This data product is a map of data counts
   for the gridded data product of the corresponding filename.
   This grid has a resolution of 500m/pix by 500m/pix, true at the pole 
   in polar stereographic (spherical) projection, and based on altimetry 
   data acquired by the MLA instrument through Mercury Orbit Year 5.
   The gridded topographic data product is the source for this data set, 
   which contains the number of observations per pixel used to produce it.
   Map values are relative to a radius of 2439.4 km.

   This label describes three objects.  The first is a JP2 file of
   the corresponding uncompressed .IMG file. A jpeg 2000 compression is used 
   to render the image.  The second is the uncompressed IMG file.  The third
   is an auxiliary xml file that contains extensible markup language that is 
   interpreted by GDAL readers (www.gdal.org).
