Nathair Facula Topography and Photometric Cube Data V1.0
This bundle contains regional topography and photometric data for two locations within Nathair Facula, Mercury. Both locations focus on volcanic vents and pyroclastic deposits near 35.86 Lat 63.93 E Lon. The data was generated using the Gaskell Stereophotoclinometry (SPC) software suite with images from the MESSENGER mission to Mercury. In addition to the topographic heights of the Digital Terrain Model (DTM), photometric data is aligned to and has the same horizontal spacing as the topographic data. For select Mercury Dual Imaging System (MDIS) Narrow Angle Camera (NAC) or Wide Angle Camera (WAC) images, four photometric data products are available; I/F (reflectance), Local Phase Angle, Local Emission Angle, and Local Incidence Angle. One DTM represents heights every 120 m and has a size of 130 by 130 km, while the other represents heights every 60 m and has a size of 80 by 80 km. The two DTMs partially overlap. -
