Mercury MESSENGER MDIS Basemap LOI Global Mosaic 166m (256ppd)
The Map Projected Low-Incidence Angle Basemap RDR (LOI) data set consists of a global monochrome map of reflectance at a resolution of 256 pixels per degree (~166 m/p).
Each original map tile, defined geographically in the same manner as for BDRs, contains a single band that merges NAC and WAC 750-nm images. This edition, version 1, was released May 13, 2016 to the Johns Hopkins Applied Physics Laboratory MESSENGER Team website. The original LOI mosaic was released at end of mission, is compiled in part based on images taken as a part of the global low-incidence angle imaging campaign but also includes any NAC or WAC 750-nm images from any campaign that best fit the intended illumination geometry, i.e., low emission angle and incidence angle near 45°. 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.
