This method consists of blending and harmonising 3D models and normalising reflectance to a global albedo map. Eleven HRSC image sets were processed to Digital Terrain Models (DTM) based on an opensource stereo photogrammetric package called CASP-GO and merged with 71 published DTMs from the HRSC team. In order to achieve high quality and complete DTM coverage, a new method was developed to combine data derived from different stereo matching approaches to achieve a uniform outcome. This new approach was developed for high-accuracy data fusion of different DTMs at dissimilar grid-spacing and provenance which employs joint 3D and image co-registration, and B-spline fitting against the global Mars Orbiter Laser Altimeter (MOLA) standard reference. Each HRSC strip is normalised against a global albedo map to ensure that the very different lighting conditions could be corrected and resulting in a tiled set of seamless mosaics. The final 3D terrain model is compared against the MOLA height reference and the results shown of this intercomparison both in altitude and planum. Visualisation and access mechanisms to the final open access products are described.<\/jats:p>","DOI":"10.3390\/rs13071385","type":"journal-article","created":{"date-parts":[[2021,4,3]],"date-time":"2021-04-03T22:03:36Z","timestamp":1617487416000},"page":"1385","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Seamless 3D Image Mapping and Mosaicing of Valles Marineris on Mars Using Orbital HRSC Stereo and Panchromatic Images"],"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 6 NT, UK"}]},{"given":"Greg","family":"Michael","sequence":"additional","affiliation":[{"name":"Department of Geosciences, Institute for Geological Sciences, Planetary Sciences and Remote Sensing, Freie Universit\u00e4t Berlin, 12249 Berlin, Germany"}]},{"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 6 NT, UK"}]},{"given":"Susan J.","family":"Conway","sequence":"additional","affiliation":[{"name":"Laboratoire de Plan\u00e9tologie et G\u00e9odynamique, CNRS, UMR 6112, Universit\u00e9 de Nantes, 44300 Nantes, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2601-6081","authenticated-orcid":false,"given":"Alfiah R.
