Dupuy, Stéphane, 2023, "Mayotte - 2022 - DHM from Pleiades stereoscopic images", https://doi.org/10.18167/DVN1/4EAKVD, CIRAD Dataverse, V2
The data published here are derived from Pleiades images acquired by the Dinamis system. These data are produced for the Biotamaya project. - The DSM (Digital Surface Model) is calculated from Pleiades images acquired in stereoscopic mode. The images were acquired in 2022 (betwee... |
