Mars DEMs – beta

High-resolution Digital Elevation Models for Mars

Digital elevation models (DEMs) provide critical information about the three-dimensional geometry of surface outcrops on other planets and can help test different hypotheses. Using open-source software the Geomorphology and Aeolian Landscape Evolution lab creates DEMs from publicly archived high-resolution stereo images of Mars. The group has made over 50 DEMs from HiRISE images at a point spacing of 1 meter-per-pixel, and even more DEMs from CTX images at a point spacing of ~6 meters-per-pixel. The lab generates these DEMs on a series of unix-based machines and the process has been automated for efficiency.

Digital elevation models created by the GALE research group from high resolution stereo imaging of Mars. A) A HiRISE image (~25 cm/px) and overlain color DEM (1 m/px) showing eroded terrain in Arabia Terra. Images ESP_016394_2045/ESP_047303_2045. B/C) A pedestal crater in (A) with a much higher interior than the surrounding plains. This elevation difference is clear with the color DEM, but not with the image alone. D) Layers on the sedimentary mound in Henry crater (see Day and Catling, 2019). PSP_007070_1915/PSP_006569_1915. E) Indurated dunes in Apollinaris
Sulci. PSP_009609_1675/PSP_010453_1675.

Requesting new DEMs

New DEMs are being made all the time in the GALE lab, and we will happily take requests for new products. Depending on the size of the images and the requested resolution, DEMs typically take between 1 and 4 days to generate (including some quality control by our researchers). Researchers interested in requesting new DEMs or accessing existing ones in the list below should contact the lab at daym@epss.ucla.edu.

A perspective view and elevation profile from a DEM made over Honeycomb Terrain in Hellas Basin Mars. This CTX DEM exaggerates the troughs and ridges from regional folding.

Full DEM list

Below is a list of all DEMs already made by the group. Eventually this list will include links to the actual data, but please excuse our construction. To request a DEM from this list or to request a specific image pair to process, please email daym@epss.ucla.edu
