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 produit Image numérique géoréférencée de carte marine est un fichier numérique, image de la carte marine imprimée correspondante du Shom ou de son (ses) cartouche(s), avec indications de géoréférencement et comprenant les mentions hors cadre.

Ces cartes sont établies sur la base de données cartographiques vectorielles (format S-57 de l'OHI) contenant la description détaillée de chaque objet (marque de balisage, épaves, câbles sous-marins, zones réglementées, sondes, etc.). Elles sont l'équivalent numérique des cartes marines papier.
