- Abstract
-
This product represents a CTX digital elevation model (DEM/DTM) mosaic at 20 m/pixel from stereo pairs covering Jezero crater. This mosaic includes the original Mars 2020 Jezero CTX TRN DEM but extends to include the entire crater with DEMs produced using Ames Stereo Pipeline (Beyer 2020). The added DEMs were localize to the Mars MOLA dataset vertically and some horizontal georeferencing was done in ArcGIS Pro.
Science Investigation orthomosaic (5m/pixel, GeoTiff), matched to the DEM.
