<em>Surface current predictions computed from statistical values obtained from the IROISE 3D 2011 Telemac hydrodynamic model gridded with a regular 30m 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>.

Lidar marine product 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. This marine product is available in two formats: a set of 3D points and a qualified terrain mesh.

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. The product "Litto3D - Nouvelle-Aquitaine 2020-2022" covers the geographical area from the Charente-Maritime to the Spanish border. For the maritime part, the data produced by Shom extend offshore down to signal extinction, approximatively 20 depth when environmental conditions are optimal. On land, the data are truncated at a limit that ensures the product retain its coastal character.
