[DREAL OCCITANIA] Litto3d by sector

The national Litto3D® program aims to produce a digital altimeter model of reference, continuous land-sea and precise, on the fringe of the metropolitan and ultramarine coastline. It uses airborne laser surveys (LIDAR) to measure depths in hard-to-reach foreshore areas, in addition to multibeam probes on board ships. Litto3D® describes the coastline: — at sea, up to the isobath 10 m and not more than 6 nautical miles from the coast, — on land, up to altitude + 10 m and at least 2 km inland. This operation, led by the Shom and the National Institute for Geographical and Forestry Information (IGN), was carried out in partnership with the Regional Directorate of Environment, Planning and Housing Languedoc-Roussillon (DREAL) and the Languedoc-Roussillon Region. Litto3D® in the Languedoc-Roussillon region is co-financed by the European Union. Europe is engaged in France with the European Regional Development Fund. The survey dates from 2009. The layer presented here corresponds to the coastline divided into an area. A link to the wording of each sector allows you to display the image of the digital field model on its right-of-way. To obtain the data, a request must be made to the coastal division of the Dreal Occitanie or on the following link: http://diffusion.shom.fr/produits/altimetrie-littorale/litto3d-lang-rouss2009.html
