Ce modèle bathymétrique (MNT) est le résultat de la compilation de données et modèles numériques antérieurs à 2008 dans la zone du Golfe de Gascogne. Le pas de la grille est de 1000 mètres. Accès tout public sous conditions.

Modèle bathymétrique (MNT) de la Zone de Protection Ecologique de Méditerranée. Les données bathymétriques dont la profondeur est supérieure à 200 m (au delà du rebord du plateau continental) proviennent des levés par sondeurs multifaisceau de l'IFREMER. Les données du plateau continental (inférieures à 200 m) proviennent des levés hydrographiques et de la base de données du SHOM. Le pas de la grille est de 250 mètres.

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). This product is available at different vertical references, either the lowest astronomical tide (LAT) or the mean sea level (MSL).

Ce modèle bathymétrique (MNT) est le résultat de la synthèse de données bathymétrique et topographique de la Manche et de la marge du golfe de Gascogne antérieure à 2008. Le pas de la grille est de 500m. Accès tout public sous conditions.

The bathymetric DEM for the coasts of Guadeloupe and Martinique with a resolution of 0.001° (~ 100 m) was prepared as part of the HOMONIM project. The DEM covers some of the Lesser Antilles islands, from Anguilla in the north to Saba in the south. The model ranges off-shore to a depth of 3275 m. 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.

The coastal topobathymetric DEM of Ré Island's surroundings, with a resolution of 0.00005° (~5 meters), was created by Shom as part of the HOMONIM-3 project. It covers the coast of the municipalities of Ars-en-Ré and Saint-Clément-des-Baleines, extending offshore to a depth of about 20 meters, to the west of the Phare des Baleines lighthouse. This DEM is designed for use in hydrodynamic models to enhance the modeling of coastal processes, particularly forecasting submersion risk. The product complements the coastal topobathymetric DEM of the Pertuis-Charentais, with a resolution of 0.0002° (~20 meters), and the bathymetric DEM of the Atlantic coast, with a resolution of 0.001° (~100 meters). It is available in the vertical reference of the Lowest Astronomical Tide (LAT) or the Mean Sea Level (MSL).

A bathymetric DEM for the coasts of Gulf of Lion – Côte d’Azur with a resolution of 0.001° (~ 100 m) was prepared as part of the HOMONIM project. It covers the entire Mediterranean metropolitan facade. The model ranges off-shore to a depth of 2800 m. 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 Saint-Martin et Saint-Barthélemy à une résolution de 0.001° (~ 100 m) a été réalisé dans le cadre du projet HOMONIM. Le MNT englobe une partie des îles des petites Antilles, depuis Anguilla au nord jusqu’à Saba au sud. Il s’étend au large jusqu’à 3275 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.

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.
