The coastal topo-bathymetric product of a part of the Norman-Breton Gulf at a resolution of 0.0002° (~ 20 m) was produced within the framework of the PAPI Saint-Malo (with the financial assistance of Saint-Malo Agglomération, the council department of Ille-et-Vilaine, of the Ministry of Ecological Transition and Shom). This coastal DEM encompasses the Minquiers plateau in the northwest to the bay of Mont-Saint-Michel in the southeast.
This DTM is intended to be implemented in hydrodynamic models in order to produce forecasts as precise as possible of water levels and sea states at the coast and therefore to improve the management of the risk of marine submersion.
This DTM is offered openly on the Shom diffusion website. https://dx.doi.org/10.17183/MNT_COTIER_GNB_PAPI_SM_20m_WGS84
