Digital Elevation Model (DEM) and orthophotography of La Palue and Lostmarc’h beaches in Crozon peninsula (France) from the photogrammetric processing of drone images (DJI Phantom 4 RTK) with a flying height of 100 m.

Orthophotos were obtained concurrently with photogrammetric DEMs. They were derived from Unmanned Aerial Vehicle (UAV) imagery processed using Structure-from-Motion photogrammetry (survey method PHO).

In order to facilitate capturing three-dimensional beach change, full surveys of the subaerial beach have been conducted starting in 2004 using RTK-GNSS (survey method GPS), Unmanned Aerial Vehicle (UAV) imagery processed using Structure-from-Motion (SfM) photogrammetry (survey method PHO) and terrestrial laser-scanning (survey method TLS). For each survey, we prepared a Digital Elevation Model (DEM) at a fixed sampling distance of 0.5 m.

Continuous tidal levels spanning the period 2000-2019 are provided alongside topo-bathymetric and wave datasets. The astronomical tide dataset starts three years before beach morphological observations. Tidal levels were derived from existing databases furnished by external organisations.
