Litto 3D : a 3D seamless representation of French coastal areas
The French national program Litto3D was
launched in April 2003 as a need for a better management of coastal areas.
It
remains the first data set coming from the collaboration of the French National
Mapping Agency (IGN) and the Hydrographic and Oceanographic Service of the
French Navy (SHOM).
Litto3D is an seamless altimetric digital elevation model
of French coastal foreshore.
Litto3D builds upon both bathymetric and
topographic lidar surveys completed by water depths measurements using
multi-beam sounder
From this results an accurate knowledge of the French wholecoastal areas (homeland andultra-peripherals: Guadeloupe, Martinique, Réunion,
Guyane, Mayotte and Saint-Pierre-et-Miquelon).
The aim of Litto3D® is to produce a seamless bathymetric and topographic database
covering the littoral zone, right now available for Brittany.
