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

A geographic package known as the "marine product" comprises data acquired using airborne topo-bathymetric and bathymetric lidar systems as part of the operation "Lidar Rance". This operation was led by Shom and co-financed by French State and the Brittany Region.

Statement

These data were acquired by airborne lidars during acquisition campaigns conducted 27th June 2019, 28th June 2019 ant 3rd September 2019. The topo-bathymetric data lidar come from a HawkEye 3 sensor in double trap configuration (Chiroptera + Deep Channel).
