Abstract

Product Information: This is a colorized shaded-relief of the original digital elevation model (DEM). Using the Integrated Software for Imagers and Spectrometers (ISIS3) and observations from Mercury Dual Imaging System (MDIS) narrow-angle camera (NAC) and multispectral wide-angle camera (WAC), we derived a global DEM of Mercury. We created the global DEM of Mercury from a least-squares bundle adjustment (jigsaw in ISIS3; Becker et al., 2016) of common features, measured as tie point coordinates in overlapping NAC and WAC-G filter images. The resolution of this DEM is 2 kilometers per pixel (km). The MDIS image inventory contains over 176,000 NAC and WAC-G observations with a very large variety of disparate geometric and illumination characteristics, and we encountered limitations to existing conventional control techniques in ISIS3 that required development of new software and techniques. Mission and Instrument Information: The MErcury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft launched on August 3rd, 2004, it entered orbit around Mercury on March 11, 2011 and ended its mission on April 30th, 2015 when it deliberately plunged into the surface or Mercury. MESSENGER was the first spacecraft to orbit Mercury and had the primary goal of studying the geology, magnetic field, and chemical composition of the planet. The science payload onboard MESSENGER included: Mercury Dual Imaging System (MDIS), Gamma-Ray Spectrometer (GRS), Neutron Spectrometer (NS), X-ray Spectrometer (XRS), Mercury Laser Altimeter (MLA), Mercury Atmospheric and Surface Composition (MACS), Energetic Particle and Plasma Spectrometer (EPPS), and Radio Science experiment (RS). The MDIS instrument suite consists of wide-angle (WAC) and narrow-angle imagers (NAC) situated on a pivot platform that enables the instruments to be pointed in specified directions.
