Technical details of the method are described, and results are demonstrated using a 4 m\/pixel Trace Gas Orbiter Colour and Stereo Surface Imaging System (CaSSIS) panchromatic image and an overlapping 6 m\/pixel Mars Reconnaissance Orbiter Context Camera (CTX) stereo pair to produce a 1 m\/pixel CaSSIS Super-Resolution Restoration (SRR) DTM for different areas over Oxia Planum on Mars\u2014the future ESA ExoMars 2022 Rosalind Franklin rover\u2019s landing site. Quantitative assessments are made using profile measurements and the counting of resolvable craters, in comparison with the publicly available 1 m\/pixel High-Resolution Imaging Experiment (HiRISE) DTM. These assessments demonstrate that the final resultant 1 m\/pixel CaSSIS DTM from the proposed processing system has achieved comparable and sometimes more detailed 3D reconstruction compared to the overlapping HiRISE DTM.<\/jats:p>","DOI":"10.3390\/rs13112185","type":"journal-article","created":{"date-parts":[[2021,6,3]],"date-time":"2021-06-03T21:03:32Z","timestamp":1622754212000},"page":"2185","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Ultra-High-Resolution 1 m\/pixel CaSSIS DTM Using Super-Resolution Restoration and Shape-from-Shading: Demonstration over Oxia Planum on Mars"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9170-6655","authenticated-orcid":false,"given":"Yu","family":"Tao","sequence":"first","affiliation":[{"name":"Imaging Group, Mullard Space Science Laboratory, Department of Space and Climate Physics, University College London, Holmbury St Mary, Surrey RH5 6NT, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sylvain","family":"Dout\u00e9","sequence":"additional","affiliation":[{"name":"Institut de Plan\u00e9tologie et d\u2019Astrophysique de Grenoble (IPAG), Universit\u00e9 Grenoble Alpes\/CNRS-INSU, UMR 5274, 38058 Grenoble, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5077-3736","authenticated-orcid":false,"given":"Jan-Peter","family":"Muller","sequence":"additional","affiliation":[{"name":"Imaging Group, Mullard Space Science Laboratory, Department of Space and Climate Physics, University College London, Holmbury St Mary, Surrey RH5 6NT, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0577-2312","authenticated-orcid":false,"given":"Susan J.","family":"Conway","sequence":"additional","affiliation":[{"name":"CNRS, UMR 6112, Laboratoire de Plan\u00e9tologie et G\u00e9odynamique, Universit\u00e9s de Nantes, 44300 Nantes, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicolas","family":"Thomas","sequence":"additional","affiliation":[{"name":"Physikalisches Institut, Universitat Bern, Sidlerstrasse 5, 3012 Bern, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriele","family":"Cremonese","sequence":"additional","affiliation":[{"name":"INAF, Osservatorio Astronomico di Padova, 35122 Padova, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,3]]},"reference":[{"key":"ref_1","first-page":"17","article-title":"August.
