Coastal topo-bathymetric MNT of the Gironde estuary – Upstream (HOMONIM project)

Description

The update of the coastal topo-bathymetric NTM of the Gironde estuary – upstream to a resolution of 0.0002° (~ 20 m) was carried out as part of the HOMONIM phase 3 project. This MNT extends over the upstream part of the Gironde estuary, from Pauillac to Bordeaux on the Garonne and to Libourne on the Dordogne. It is complementary to the MNT covering the downstream estuary (between Pauillac and the mouth of the Gironde). The NTM is intended to be implemented in hydrodynamic models to produce as accurate forecasts as possible of the heights of water and sea states to the coast in order 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.
