Litto3D® is a unique and continuous land-sea database which provide 3D models of french coastal areas. Surveys are carried out by airborne lidar bathymetry over the sea side and airborne lidar topography over the land up to 2km inland. Litto3D® digital models are available in two formats: a set of 3D points and a digital terrain model. The product "Litto3D® - Brittany 2018-2021" covers the coastline and islands of Côtes d'Armor, Ille-et-Vilaine and Morbihan departments.

Litto3D marine part 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. Litto3D marine part digital models are available in two formats: a set of 3D points and a qualified terrain mesh. The product "Litto3D marine part - Nouvelle-Aquitaine 2020-2022" covers the geographical area from the Sèvre Niortaise to the Spanish border.

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.

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 Sèvre Niortaise to the Spanish border.
