Coastal topo-bathymetric DEM for the Pertuis of Charente(HOMONIM project)
The update of the coastal topo-bathymetric DEM of the Pertuis charentais at a resolution of 0.0002° (~ 20 m) was carried out in the third phase of the HOMONIM project.
The DEM extends from the terrestrial domain to about 60 meters depth over all the pertuis (pertuis Breton, pertuis d’Antioche and pertuis of Maumusson).
The DEM is intended to be implemented in hydrodynamic models in order to produce forecasts as accurate as possible of water heights and sea states at the coast to improve the relevance of the Wave-Submergence Vigilance.
This product is available with either the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical reference.

In addition to the Shom data, the surveys of external organizations were exploited. Those contributors are the following :
Délégation à la Mer et au Littoral de la Vendée
DDTM de Charente-Maritime
Grand Port Maritime de Bordeaux
Grand Port Maritime de La Rochelle
IGN (RGEALTI® V2.0)
Laboratoire Central d'Hydraulique de France
- Description
-
The main production tasks of this product line are based on 4 major axes each aiming at reducing the DTM uncertainties:
1) the collection, evaluation, pre-processing, and selection of data from multiple sources whose acquisition is from different sensors and time periods;
2) homogenization of the vertical and horizontal reference of the data sets;
3) the use of interpolation algorithms adapted to the heterogeneous distribution and variable density of the data, and
4) the evaluation and qualification of the final product and the elaboration of its documentation
