Abstract

The French National Geographic Institute (IGN) and the French Naval Hydrographie and Oceanographic Office (SHOM) were tasked by the Prime Minister to combine efforts to produce a seamless, precise topographic and bathymetric model, of the entire French coast. The Litto3D project was then created to meet more than one hundred requirements expressed by coastal managers and by users of geo-referenced data. An initial laser survey was conducted in the Golfe du Morbihan, Brittany and was used to generate a precise DTM. This experiment enabled SHOM and IGN to develop a methodology applicable everywhere and by everyone.
