https://community.esri.com/t5/arcgis-image-analyst-questions/dtm-extraction-corona-images/m-p/1309084#M475 <P>I am trying to extract a DTM from 3 Corona images for the Luxor, Egypt area (Corona Mission 1107, dataset name: DS1107-1090DA99, 100 and 101). The images are orthorectified and do not need georeferencing or adjustment(s). I tried to follow the doc available at<SPAN>&nbsp;</SPAN><A href="https://pro.arcgis.com/en/pro-app/latest/help/data/imagery/ortho-mapping-in-arcgis-pro.htm" target="_blank" rel="nofollow noopener noreferrer">https://pro.arcgis.com/en/pro-app/latest/help/data/imagery/ortho-mapping-in-arcgis-pro.htm</A><SPAN>&nbsp;</SPAN>, first creating the orthomosaic and then the DTM. However, the process stops (ERROR 003048: The input folder does not contain LAS files). I usually use Aster or Alos product so I'm not familiar with DTM/DSM extraction .. Has anyone already extracted DTM or DSM from Corona images or similar with Ortho Mapping in Pro and could give me some hints?</P><P>Thanks!</P> Tue, 18 Jul 2023 14:33:35 GMT GiuliaNicatore 2023-07-18T14:33:35Z https://community.esri.com/t5/arcgis-image-analyst-questions/dtm-extraction-corona-images/m-p/1309084#M475 <P>I am trying to extract a DTM from 3 Corona images for the Luxor, Egypt area (Corona Mission 1107, dataset name: DS1107-1090DA99, 100 and 101).
