Faults in Ius Chasma
One of the derived products from the HiRISE experiment is the production of digital elevation models (DEMs). These DEMs provide unprecedented details of the topography of Mars, and are made from two areas of the same area on the ground, taken from slightly different look angles. As a general guide, terrain can be derived at a post spacing about 4 times the pixel scale of the input image, so that the DEM post spacing is 1 – 2 m with vertical precision in the tens of centimeters range. Thus these data are produced in a different manner from the DEM shown this month in image PRPDC-0031.
This image shows different elevations as a color rainbow, with the highest point at an elevation of -2405 m, and the lowest point at -3137 m. It covers part of the floor of Valles Marineris, centered at 7.82oS, 279.49oE (see below image) and could be used for numerous structural studies.
