  • The “World Seabed Sediment Map” product contains geo-referenced digital data, describing the nature of the sediment encountered in different seas and oceans of the world. The objects are all surface areas and the description of an object includes in particular the nature of the sediment including rock-type bottoms.

  • <em>Surface current predictions computed from statistical values obtained from the IROISE 3D 2011 Telemac hydrodynamic model gridded with a regular 500m spatial resolution.</em><br /> <br /> This service offers a visualization of surface current predictions computed from statistical values obtained from a high resolution hydrodynamic simulation at mean Neap and Spring corresponding to a tide coefficient of respectively 45 and 95. Those statistics are then interpolated/extrapolated every 15 minutes (cubic spline), and for each tide coefficient from 20 to 120 (linear). The statistical currents, initially referenced to Brest high tide, are then referenced to the hour requested by the user using the tide prediction service <a href="http://maree.shom.fr" target="_blank">http://maree.shom.fr</a>.

  • Litto3D Marine Part is an intermediate product of the Litto3D product containing only marine data.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.

  • Litto3D provides 3D, continuous sea-land description of French coastal areas. Data is acquired by airborne topo-bathymetric LiDARs. Litto3D products come in 3D point clouds and digital terrain models formats. Litto3D Saint-Pierre-and-Miquelon product covers land area of the islands as well as bathymetry down to approx. 20m.

  • French Ministry of Agriculture and Food / DRASSM - Shom<br /> The product "Limits related to fishery uses" contains the limits related to fishery uses as defined in the French or European legislations. Those limits are managed by the Directorate for Sea Fisheries and Aquaculture (DPMA) of the Ministry of Agriculture and Food. <br /> Those limits are divided into three categories : <br /> - the inner limit of the coastal waters (6 nautical miles) ; <br /> - the 3-nautical-mile limit ; <br /> - the limit of fisheries for overseas territories (100 nautical miles).<br /><br /> The product "Limits related to fishery uses" is to use in addition to the digital product “Maritime Limits and Boundaries” of Shom (French: “Délimitations maritimes”) which represents the limits of the French maritime spaces of sovereignty or jurisdiction through the World.<br /> The product “Maritime Limits and Boundaries” (French: “Délimitations maritimes”) can be viewed on data.shom.fr (Maritime boundaries Category) and downloaded on the French national portal of maritime limits (https://maritimelimits.gouv.fr).

  • 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. <br /> October 27 2025 version

  • 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
