Litto3D - Nouvelle-Aquitaine 2020-2022
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 Charente-Maritime to the Spanish border. For the maritime part, the data produced by Shom extend offshore down to signal extinction, approximatively 20 depth when environmental conditions are optimal. On land, the data are truncated at a limit that ensures the product retain its coastal character.

- Purpose
-
The main aim is to produce precise digital data with unrivalled resolution (decimetric precision, metric resolution) for french coastal terrain. This solution provides the basic data required to implement many applications and public policies, such as:
• risk prevention (tsunamis, cyclone swell, rising sea level due to global warming, coastal flooding, flooding, erosion, etc.),
• coastal planning studies (roads, ports, etc.),
• improved knowledge of the public maritime territory, tracking coastal withdrawal,
• mapping terrestrial and marine habitats,
• creating current models and related applications (tidal and swell current energy, waste dispersal at sea, sedimentary movements, etc.),
• Integrated Coastal Zone Management (ICZM).

This operation was led by Shom and IGN (French institute for geographical and forestry information) in partnership with French ministry for Environment, the Nouvelle-Aquitaine Region and the European Union within the framework of the European Regional Development Fund (FEDER).

These data were acquired by airborne lidars during acquisition campaigns conducted from 7 September 2020 to 29 October 2020, from 30 August 2021 to 30 October 2021 and from 15 April 2022 to 18 June 2022. The topo-bathymetric data lidar come from a HawkEye 3 sensor in double trap configuration (Chiroptera + Deep Channel). Data on land were acquired during the IGN's compaign "LIDAR HD", between 8 May 2021 and 1 October 2023.
