The Corsican facade bathymetry product with a resolution of 0.001° (~ 111 m) was produced as part of the HOMONIM project. It covers the entire Corsican margin, from the coast to about 3000 m deep. The DEM is intended to be implemented in hydrodynamic models in order to produce the most accurate forecasts possible of water levels and sea states at the coast and therefore to improve the relevance of Wave-Submersion Vigilance. This product is available with the lowest astronomical tide level (PBMA) or the mean sea level (NM) as a vertical reference.
