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.

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.

In the absence of a maritime boundary agreement with a neighbouring State, the French Republic can unilateraly claim a delimitation. This boundary has indeed a provisional aspect pending the ratification of a boundary agreement. The theme "Maritime limits unilaterally claimed" gathers those limits unilaterally claimed by France. Some of those elkements are published by decree.

The combined error grid of the SIO V31 gravity anomaly model (D. T. Sandwell, H. Harper, B. Tozer et al., Gravity field recovery from geodetic altimeter missions, Advances in Space Research, https://doi.org/10.1016/j.asr.2019.09.011) is computed with a method described in a paper submitted to Earth and Space Science (AGU). The model’s extension is North Atlantic.
