Il couvre l’intégralité de la façade métropolitaine méditerranéenne, du littoral jusqu’à environ 2800 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. Ce produit est disponible avec comme référence verticale le niveau des plus basses mers astronomiques (PBMA) ou le niveau moyen des mers (NM). 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. ©Shom Shom 13 rue du Chatellier Brest 29200 France support@shom-support.zendesk.com https://services.data.shom.fr/static/imagettes/MD/mntMed.PNG thumbnail png https://services.data.shom.fr/static/imagettes/MD/mntMed.PNG large_thumbnail png Altitude Elevation GEMET - INSPIRE themes, version 1.0 2008-06-01 publication bathymétrie bathymetry Modèle Numérique de Terrain digital elevation model Produit Product données ouvertes open data Golfe du Lion Côte d'Azur Mer Méditerranée Géophysique Geophysic Nationales INSPIRE Spatial scope 2019-05-22 Observation de la terre et environnement High-value dataset categories 2023-09-27 Utilisation libre sous réserve de citer les sources de la manière suivante : "Shom,2015.

These are processed and quality controlled. A further refinement and expansion is underway, by gathering additional survey data sets, expanding geographical coverage to all European sea regions and upgrading the DTM grid resolution, and will result in new releases in time.

Les principales tâches de production de cette gamme de produits s’articulent autour de 4 axes majeurs visant chacun à réduire les incertitudes du MNT : 1) le recueil, l’évaluation, le pré-traitement et la sélection de données de sources multiples dont l’acquisition est issue de capteurs et d’époques différentes ; 2) l’homogénéisation de la référence verticale et horizontale des jeux de données ; 3) l’utilisation d’algorithmes d’interpolation adaptés à la répartition hétérogène et à la densité variable des données, et 4) l’évaluation et la qualification du produit finalisé et l’élaboration de sa documentation. The main tasks involved in producing this range of solutions are based on 4 key aspects, each intended to reduce uncertainty for the DEM: 1) collecting, evaluating, pre-processing and selecting data from multiple sources after acquisition using survey systems from various eras; 2) homogenising the vertical and horizontal datums for data sets; 3) using interpolation algorithms suitable for a heterogeneous distribution and the variable density of data, and 4) evaluating and qualifying the final product and preparing documentation.
