Lidar Corsica 2017-2018

Lidar marine part is a unique and continuous land-sea database which can provide 3D models of the shape and location of French coastal terrain. A line separates sea and land data acquisition zones, and the associated survey readings obtained using bathymetric lidar technologies or multibeam echosounders for sea readings and airborne lidar topographical surveys for land readings, with 300 m overlap. Litto3D digital models are available in two formats: a set of 3D points and a qualified terrain mesh.

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 "Coastal risks, LITTO3D" constitute a geographical product called "marine part". This operation was led by the Corsican Community, the Regional Directorate for the Environment, Planning and Housing of Corsica (DREAL) and Shom.

Europe is committed to Corsica.

Statement

These data were acquired by airborne lidars during acquisition campaigns conducted from 05 October 2017 to 17 October 2017, from 01 February 2018 to 26 March 2018 and from 01 September 2018 to October 03, 2018. The topo-bathymetric data lidar come from a HawkEye 3 sensor in double trap configuration (Chiroptera + Deep Channel).
