Orthomosaics of the study area surveyed by drone on October 10 and November 9, 2022 generated from 1,356 images (October 10) and 1,288 RGB images (November 9), acquired using the RTK eBee X drone and the S.O.D.A 3D camera, with a resolution of 2.9 cm/pixel. The surveyed area covers 1.95 km² in October and 1.56 km² in November. The campaign was conducted on October 10 and November 9, 2022, for Xavier Bertin (LIENSs) to measure morphological changes. The drone acquisitions were carried out by Nicolas Lachaussée from the LIENSs UMR Drone Platform. Photogrammetric processing was performed by Natacha Volto (LIENSs) using Agisoft Metashape software.
