DESCRIPTION               = "This data product is a shape map (radius)
   of Mercury at a resolution of 16 pix/deg by 16 pix/deg,
   based on altimetry data acquired through Mercury Orbit Year 5 by the MLA
   instrument. This JP2 file is an alternate format for the data given in the
   IMG file of the same name.  MLA altimetry data are the source for this 
   data set. Ground tracks were interpolated using the Generic Mapping Tools
   program 'surface'. The map is in the form of a binary table with one row 
   for each 0.0625 degrees of latitude, pixel registered.  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).
