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.

Digital Elevation Model (DEM) and orthophotography of La Palue and Lostmarc’h beaches in Crozon peninsula derived from the photogrammetric processing of drone images (Mavic 3E RTK) with a flying height of 100 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.
