Litto3D is a unique and continuous land-sea database which can provide 3D models of the shape and location of French coastal terrain. A line separates sea and land data acquisition zones, and the associated survey readings obtained using bathymetric lidar technologies or multibeam echosounders for sea readings and airborne lidar topographical surveys for land readings, with 300 m overlap. Litto3D digital models are available in two formats: a set of 3D points and a qualified terrain mesh.

The Tidal stream atlas netcdf product – Northern Brittany provides tidal current data for an area stretching from Tregastel at the east of the area to Porsguen at the west. The product consists of two gridded files with different spatial resolutions covering the Northern Brittany area (overall view at 500 m) and the geographical area of the port of Roscoff (250 m). The U and V velocities of the tidal currents depend on the tidal conditions considered at mean neap and spring tidal rates. The data are provided in m/s for the surface layer. The times are given in relation to high tide at the reference port chosen in the area and are provided from 6 hours before to 6 hours after that reference.

Litto3D marine part is a unique and continuous land-sea database which can provide 3D models of the shape and location of french coastal terrain. Surveys are carried out by airborne lidar bathymetry over the sea side and airborne lidar topography over the land side up to 400m inland. Litto3D marine part digital models are available in two formats: a set of 3D points and a qualified terrain mesh.

The product "Wrecks and obstructions" contains a description of wrecks and obstructions in the French Exclusive Economic Zone (EEZ) as 2D point objects. Objects of the product "Wrecks and obstructions" are divided into 2 classes: - Wrecks (WRECKS): all or part of a stranded or sunken ship or aircraft; - Obstructions (OBSTRN): object of an artificial nature other than a wreck (for example: container, lost anchor). This product does not concern floating or drifting objects (containers, debris, buoys out of position, ...) which position changes rapidly. <br /> February 17 2026 version
