The datum of Digital Elevation Model of North Pole of Moon, included in the archive, derived from raster data of Lunar Orbiter Laser Altimeter (LOLA) experiment, version 2.0, which was part of Lunar Reconnaissance Orbiter (LRO) mission, and distributed by Planetary Data System (PDS) of NASA. The datum has multiple resolutions, utilizing data resolution from 100m to 5m. 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 set of spatial regions representing limiting areas for each primary used data of respective resolutions.
