Topographic map of Venus in conformal projections, consisting of a map in Mercator projection centered on zero longitude and latitude and two polar maps in stereographic projection. The Mercator projection is used between the 66.513◦ parallels and the polar stereographic projections are used for the polar regions north and south of the 60◦ parallels. Maps are projected on sphere with a mean radius of 6 051.0 km. Main sources for this map are image data from the Magellan Synthetic Aperture Radar (SAR) and altimetry data from Magellan’s altimeter
This map is based on data from the Mars Odyssey’s Thermal Emission Imaging System (THEMIS), Mars Global Surveyor’s (MGS) laser altimeter (MOLA), Mars Express’ (MEx) High Resolution Stereo Camera (HRSC) and Mars Reconnaissance Orbiter’s (MRO) Context Camera (CTX). Base map is combination of shaded relief map and color coded elevation map derived from digital elevation model data derived from the Mars Orbiter Laser Altimeter (MOLA) and the High-Resolution Stereo Camera (HRSC) dataset (Ferguson et al. 2017) and THEMIS-IR day global mosaic (Edwards et al. 2011). Gaps in the THEMIS data around both poles were filled with data from the images taken by Mars Express’ HRSC camera (Roatsch 2015). Reprojection of all maps was done via Map-a-Planet 2 application (MAP2 2018).
