MNT bathymetric facade of the Gulf of Lion – Côte d’Azur (Project HOMONIM)

The bathymetry product Gulf of the Lion – Côte d’Azur with a resolution of 0.001° (~ 111 m) was produced as part of the HOMONIM project. It covers the entire Mediterranean metropolitan façade, from the coastline to about 2 800 m deep. The NTM is intended to be implemented in hydrodynamic models in order to produce as accurate forecasts as possible of the heights of water and sea states at the coast and thus to improve the relevance of the Vigilance Vagues-Submersion. This product is available with the lowest astronomical sea level (PBMA) or mean sea level (NM) as a vertical reference.分辨率为0.001°（约111米）的利翁湾-蔚蓝海岸水深地形数据产品，系HOMONIM项目的研制成果。该产品覆盖整个地中海滨海都市区岸线范围，从海岸线延伸至约2800米水深区域。该NTM模型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高度与海况，进而提升海浪-淹没警戒预警体系的实用性与预警准确性。该产品可采用最低天文潮位（PBMA）或平均海平面（NM）作为垂直基准面。
