Coastal topo-bathymetric DEM for the Boulogne-sur-Mer harbor and the surrounding area (TANDEM project)

The coastal topo- bathymetric DEM for the coasts of Boulogne-Sur-Mer with a resolution of 0.0001° (~ 10 m) was prepared as part of the TANDEM project (Programme Investissements d'Avenir, ANR-11-RSNR-00023-01). The DEM covers the entire Boulogne-sur-Mer port, from north of Wimereux to south of the Boulogne-sur-Mer urban sprawl. The DEM is designed to be implemented in the hydrodynamic models of the TANDEM project in order to estimate the coastal effects of tsunamis for the Atlantic and English Channel, where French nuclear power plants have been installed for about 30 years. This product is available with the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical datum.
