The coastal topo- bathymetric DEM for the coasts of the Saint-Jean-de-Luz bay with a resolution of 0.0002° (~ 20 m) was prepared as part of the TANDEM project. It covers Saint-Jean-de-Luz bay and the surrounding area. The DEM is designed to be implemented in the hydrodynamic models of the TANDEM project in order to estimate the coastal effects of tsunamis for the Atlantic and English Channel, where French nuclear power plants have been installed for about 30 years. This product is available with the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical datum.

Le MNT topo-bathymétrique côtier d'une partie du golfe normand-breton à une résolution de 0.0002° (~ 20 m) a été réalisé dans le cadre du PAPI Saint-Malo. Le MNT englobe le plateau des Minquiers au Nord-Ouest jusqu'à la baie du Mont-Saint-Michel au Sud-Est. Le MNT est destiné à être implémenté dans les modèles hydrodynamiques afin de produire des prévisions aussi précises que possible des hauteurs d’eau et d’états de mer à la côte et donc d’améliorer la gestion du risque de submersion marine.

The coastal topo- bathymetric DEM for the coasts of the straight of Pas-de-Calais with a resolution of 0.0002° (~ 20 m) was prepared as part of the TANDEM project. The DEM covers the eastern Channel and southern North Sea, including the French coast of the Nord - Pas-de-Calais administrative department and part of the British coast, in the county of Kent, and the south part of the Thames estuary up to Rye. The DEM is designed to be implemented in the hydrodynamic models of the TANDEM project in order to estimate the coastal effects of tsunamis for the Atlantic and English Channel, where French nuclear power plants have been installed for about 30 years. This product is available with the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical datum.

The coastal topo-bathymetric DEM of Moorea with a resolution of 0.0002° (~ 20 m) was produced by the Shom for Météo-France (Inter-regional Direction in French Polynesia). This DEM covers the Moorea lagoons down to the 100 m isobath, in order to meet the need for modeling marine submersions in French Polynesia. It complements the bathymetric DEM of Tahiti and Moorea, with a resolution of 0.001° (~ 100 m). The vertical reference for this product is the Lowest Astronomical Tide (LAT).

The update of the coastal topo-bathymetric DEM of the Gironde estuary - downstream with a resolution of 0.0002° (~ 20 m) was carried out in the third phase of the HOMONIM project. This DEM covers the downstream part of the Gironde estuary, from Pauillac to its mouth. It is complementary to the DEM covering the upstream estuary. 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. The vertical reference for this product is Mean Sea Level (MSL).

The bathymetric DEM of Tahiti and Moorea with a resolution of 0.001° (~ 100 m) was produced by the Shom for Météo-France (Inter-regional Direction in French Polynesia). This DEM covers a 10 km radius around the islands of Tahiti and Moorea in order to meet the need for marine submersions modelling in French Polynesia. The vertical reference for this product is the Lowest Astronomical Tide (LAT).

The bathymetric DEM of the atlantic facade with a resolution of 0.001° (~ 100 m) was prepared as part of the HOMONIM project. It encompasses part of the North Sea, the Channel and the Bay of Biscay. Offshore, this DTM extends beyond the slope to approximately 4800 m depth. The DEM is designed to be used in hydrodynamic models in order to produce high-precision forecasts for coastal water levels and sea conditions and therefore improve the pertinence of the Waves-Submersion monitoring programme. This product is available with the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical datum.

Le MNT bathymétrique de façade de Mayotte à une résolution de 0.001° (~ 111 m) a été réalisé dans le cadre du projet HOMONIM. Il couvre intégralement l'île de Mayotte et s'étend à l'Ouest sur l'île d'Anjouan. Le MNT s'étend au large jusqu'à 3700 m de profondeur. Le MNT est destiné à être implémenté dans les modèles hydrodynamiques afin de produire des prévisions aussi précises que possible des hauteurs d’eau et d’états de mer à la côte et donc d’améliorer la pertinence de la Vigilance Vagues-Submersion.

Le MNT topo-bathymétrique côtier du port de Saint-Malo et ses abords à une résolution de 0.00005° (~ 5 m) a été réalisé dans le cadre du PAPI Saint-Malo. Le MNT englobe la ville de Saint-Malo et ses abords, depuis la pointe du Décollé à l'Ouest jusqu'à la pointe de la Varde à l'Est. Le MNT est destiné à être implémenté dans les modèles hydrodynamiques afin de produire des prévisions aussi précises que possible des hauteurs d’eau et d’états de mer à la côte et donc d’améliorer la gestion du risque de submersion marine.

The coastal topo- bathymetric DEM of a part of the Norman-Breton gulf with a resolution of 0.0002° (~ 20 m) was prepared as part of the PAPI Saint-Malo. It covers the Minquiers plateau in the north-west to the bay of Mont-Saint-Michel in the south-east. The DEM is designed to be implemented in the hydrodynamic models of the TANDEM project in order to estimate the coastal effects of tsunamis for the Atlantic and English Channel, where French nuclear power plants have been installed for about 30 years. This product is available with the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical datum.
