2m resolution DEM based stereoscopy Pleiades acquisitions in Telangana, South-India

Four steroscopy pairs of Pléiades images (Pléiades © CNES 2021 Distribution AIRBUS DS) were acquired over Telangana state in 01 and 14 of June 2016 and the 16 of June 2019 and licensed to CESBIO by Airbus. The Pléiades Digital Elevation Model is a derivative product subject to the CC-BY-NC 4.0 license preventing commercial use. The four .tif files correspond to these DEM at 2m resolution. The dates were selected because the Rainwater Harvesting System small reservoirs of the areas covered were empty. Elevations within small reservoirs are thus equivalent to a bathymetry. We verified that 2 meter resolution is very adapted to retrieve the geometries of narrow and steep dikes that dam each small reservoirs.
