MESSENGER MDIS MAP PROJECTED MULTISPECTRAL RDR V1.0

This dataset includes the Multispectral Reduced Data Records for the WAC. The Map Projected Multispectral RDR (MDR) data set consists of a global color map of I/F in the 8 filters used for multispectral mapping during the primary mission, photometrically normalized to a solar incidence angle (i) = 30 degrees, emission angle (e) = 0 degrees, and phase angle (g) = 30 degrees at a spatial sampling of 64 pixels per degree.

The map is divided into 54 segments or 'tiles', each representing the NW, NE, SW, or SE quadrant of one of the 13 non-polar or one of the 2 polar quadrangles or 'Mercury charts' already defined by the USGS. Each tile is composed of 8 bands corresponding to 8 of the 11 WAC filters. Each tile also contains backplanes describing ancillary information.
