Bathymetric datasets are an extraction of surveys belonging to the Shom public database. For depth up to 50m, the vertical precision of soundings varies from 30cm to 1m and the horizontal precision varies from 1 to 20m. In deep ocean, the vertical precision is mainly around 1 or 2% of the bottom depth. It is sometimes more, it depends on the technology used. The data are referenced to ZH which is assimilated to LAT. Data are corrected for sound velocity variations. Data are acquired during the campaign S198502000 (http://dx.doi.org/10.17183/S198502000). // Instruments: Sondeur DESO 20 | Sondeur latéral // Number of soundings: 98042

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.
