MESSENGER MERCURY MDIS LEVEL 5 DEM V1.0
Listed in NASA Data Portal
Abstract ======== The MESSENGER MDIS DEMs are derived products.
Description
A DEM is a gridded (raster) product that records elevation values of a given terrain in each pixel. Corresponding metadata include map projection information so pixels can be associated with latitude and longitude.
Values are measured relative to the planetary geoid reference radius of 2,439.4 km (i.e. elevation). Generally, the MESSENGER DEM products described here are derived from MESSENGER MDIS image data. The DEMs are typically derived using stereo photogrammetry (i.e., stereo pairs or sets) techniques.

The primary PDS product is a DEM provided in both PDS image (.IMG) and JPEG 2000 (.JP2) format files. Associated with some of the DEM products is a list of lower-level MDIS products provided either as an accompanying table (*.TAB) file or as text (*.TXT) files in the EXTRAS directory.
