The Tidal stream atlas netcdf product – Seine Bay provides tidal current data for an area stretching from Fecamp at the east of the area to Cherbourg at the west. The product consists of two gridded files with different spatial resolutions covering the Seine Bay area (overall view at 500 m) and the geographical area of Le Havre harbour (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 or low tide at the reference port chosen in the area and are provided from 6 hours before to 6 hours after that reference.

This service allows users to view surface tidal current predictions calculated from the analysis of a high-resolution hydrodynamic simulation projected onto a 100 m grid. This service was built by Shom and funded by French CCI Métropolitaine Bretagne Ouest in the frame of the Atlantic Blue Port project of <a href="https://www.atlanticarea.eu" target="_blank">Interreg Atlantic Area</a> european program.

The Tidal stream atlas netcdf product – Strait of Dover provides tidal current data for an area stretching from the coast of Flanders east of Dunkirk to Saint-Valery-en-Caux. The product consists of four gridded files with different spatial resolutions covering the Strait of Dover area (overall view at 500 m) and the geographical areas of the ports of Dunkirk (250 m), Calais (250 m) and Boulogne-sur-Mer (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 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 "Military practice areas" product contains vector data in the form of 2D surface objects describing the military practice areas in the France sector represented on Zonex variants of nautical charts. This is the S-57 MIPARE object class (military practice areas): maritime zone within which military, naval or air exercises can take place.

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.

Lidar marine part 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 product Taharuu 2015 V. 20160630 corresponds to the zone: Mouth of Taharuu.
