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 057 France - Sein (ile) Nord (ZH) which is assimilated to LAT. Data are corrected for sound velocity variations. Data are acquired during the campaign S188400200 (http://dx.doi.org/10.17183/S188400200). // Instruments: Plomb de sonde // Number of soundings: 791 // DOI: http://dx.doi.org/10.17183/LOTS_BATHY#S188400200-4

Litto3D Partie maritime est un produit intermédiaire du produit Litto3D ne contenant que les données maritimes. Le produit Litto3D est une base de données altimétrique unique et continue terre-mer donnant une représentation tridimensionnelle de la forme et de la position du sol sur la frange littorale du territoire français. Une ligne de partage des zones d'acquisition entre terre et mer, sépare les levés réalisés par les technologies lidar bathymétriques ou sondeur multifaisceau côté mer et lidar topographiques aéroportés côté terre, un recouvrement de 300m étant prévu. Litto3D Partie maritime est disponible sous deux formes : un semis de points tridimensionnels et un modèle numérique de terrain maillé et qualifié.
