Compilation of marine gravity surveys acquired in the Northeast Atlantic by Shom between 2001 and 2016. These surveys were compiled to perform a quantification of the error of the gravity anomaly models derived from satellite altimetry. This dataset represents more than 22,000 measurement points distributed in 9 ascii survey files sampled at 1 kilometer. The file’s format is as follows: longitude latitude Gravity_anomaly error line_label.

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 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.
