Abstract

The Map Projected Basemap RDR (BDR) data set consists of a global monochrome map of reflectance at a resolution of 256 pixels per degree (~166 m/p). This edition, version 1, was released May 6, 2016 to the Planetary Data System (PDS) MESSENGER archive. It is compiled using NAC or WAC 750-nm images from any campaign that best fit the intended illumination geometry or low emission angle and incidence angle near 74°. It is controlled and projected onto a global digital elevation model. It uses a Kasseleinin-Shkuratov photometric model, whose parameters are the same for any given wavelength band across all MESSENGER end-of-mission map data products. This mosaic contains data acquired by the MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) Mercury Dual Imaging System (MDIS) instrument.

It is compiled using NAC or WAC 750-nm images from any campaign that best fit the intended illumination geometry or low emission angle and incidence angle near 74°.

Completeness Report

There are no large data gaps within the mosaic.

Process Description

For this 8bit version, the original PDS tiles were reprojected into Simple Cylindrical and original band 1 reflectance values (I/F) were stretch to 8bit (0 to 255) using min=0.0005 to a max=0.25. All other bands were removed.
