System (PDS) of NASA. The datum has resolution 1000m. The data uses Polar Stereographic 
Projection with true scale latitude of 90°.
  The datum presented here generally in form of .ZRS-files (stands Zipped Raster Set), 
which is proprietary compressed format of author of the datum. Separated files of the
