Examples of processed data obtained from ASV and UAV raw data in the west part of Reunion island: (a) Example of a bathymetric map obtained from data collected by the ASV echosounder (b) Example of underwater ASV images georeferenced using differential GPS (c) Example of a distribution map of the presence of branching acropora computed with a DinoV2 vision transformer trained on the annotated data of Seatizen Atlas and used to automatically make predictions on unnanotated images (d) Example of an underwater orthophoto obtained from georeferenced ASV images, using SfM techniques and the opensource software OpenDroneMap.
