The CTX Digital Terrain Model (DTM) products generated by the USGS Astrogeology Science Center for the Mars 2020 landing site characterization are publicly available in the PDS Annex. All CTX DTMs generated for this effort are linked below:

Several product types are available, including DTMs, orthoimages, and slope maps. The orthoimages and slope maps are listed under “Derived Products” on each DTM product page. The orthoimages and slope product pages also contain links back to the DTM they were derived from.
USGS Astrogeology also generated HiRISE DTMs for Mars 2020 landing site selection, and those DTMs are all available via the HiRISE DTM release page (https://www.uahirise.org/dtm/).
