Coastal topo-bathymetric MNT of part of the Norman-Breton Gulf

The coastal topo-bathymetric MNT of part of the Norman-Breton Gulf at a resolution of 0.0002° (~ 20 m) was carried out as part of the Saint-Malo PAPI. The NTM encompasses the Minquiers Plateau in the northwest to Mont-Saint-Michel Bay in the southeast. The NTM is intended to be implemented in hydrodynamic models in order to produce as accurate predictions as possible of the heights of water and sea states at the coast and thus to improve the management of the risk of marine submersion. This product is available with the lowest astronomical sea level (PBMA) or mean sea level (NM) as a vertical reference.
