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).

Credit

The data acquired by topographic, topo-bathymetric and bathymetric lidar airborne in the context of the operation " Litto3D® Brittany" constitute a geographical product called "marine part". This operation was led by Shom and IGN (French institute for geographical and forestry information) in partnership with French State, the Nouvelle-Aquitaine Region and the European Union within the framework of the European Regional Development Fund (FEDER).

Statement

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).
