Mercury MESSENGER-MDIS-LOI-166m survey collection

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 45deg. 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.
