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.作为圣马洛PAPI项目的组成部分，诺曼-布列塔尼海湾部分区域的海岸地形测深数字地形模型（coastal topo-bathymetric MNT）已完成研制，其空间分辨率为0.0002°（约20米）。 该数字地形模型（NTM）的覆盖范围涵盖西北侧的曼基耶尔高原至东南侧的圣米歇尔山湾。 该数字地形模型（NTM）旨在应用于水动力模型，以尽可能精准地预测海岸区域的水位与海况，进而提升海洋淹没风险的管理水平。 该产品可选用最低天文海平面（PBMA）或平均海平面（NM）作为垂直基准面。
