UAV photogrammetry monitoring of La Palue and Lostmarc'h embayed beaches (Crozon, France)

UAV flights (DJI Phantom 4 RTK - DJI Mavic M3E RTK - eBee X RTK) and GNSS surveys are performed quarterly during spring low tides over La Palue and Lostmarc’h embayed beaches in Crozon peninsula (Brittany, France). Image blocks are processed using Structure-from-Motion (SfM) photogrammetry to produce georeferenced orthophotographs and Digital Elevation Models (DEMs) at 0.1 m and 1 m spatial resolution.
