Position of the coastline of the Aquitaine sandy coastline and the Arcachon Basin in 2016

The coastline on the sandy coast corresponds to the foot of the dune. This ribline was determined by photo-interpretation of orthophotography 2016 (©IGN, OCA 2016), supported by synchronously acquired LiDAR data at orthophotography. The dune foot corresponds to the topographic rupture between the ocean duary front and the beach.
