The datum of Digital Elevation Model of North Pole of Mercury, included in the archive, derived from raster data of Mercury Laser Altimeter (MLA) Mapping Phase, version 2 of MESSENGER mission, and distributed by Planetary Data System (PDS) of NASA. Base resolution of the datum is 250m. Also data with auxiliary resolutions of 500m and 1000m was used too. 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 datum are in hierarchical and multi-resolution relation for optimization of speed and appearance upon using in Spatial Aspect Viewer and Spatial Aspect Explorer.
Also the datum contents sparse set of spatial regions covering main features of North Pole of Mercury.
