MNT topo-bathymetric coastal of the bay of Saint-Jean-de-Luz and its surroundings at 20 m (TANDEM project)

The coastal topo-bathymetric product of the Bay of Saint-Jean-de-Luz and its surroundings, at a resolution of 0.0002° (~20 m), was produced as part of the TANDEM project. It covers a territory comprising the Bay of Saint-Jean-de-Luz and its immediate surroundings. This NTM is intended to be implemented in the hydrodynamic models of the TANDEM project in order to estimate the coastal effects of tsunamis for the Atlantic and Channel, where French nuclear power plants have been installed for about 30 years. This product is available with the lowest astronomical sea level (PBMA) or mean sea level (NM) as a vertical reference.
