  LITTO3D® marine part Languedoc Roussillon 2014-2015

Litto3D Marine Part is an intermediate product of the Litto3D product containing only marine data.Litto3D 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 bathymetric data acquired by airborne bathymetric lidar as part of the Litto3D® Languedoc-Roussillon 2014-2015 operation constitute the "marine part" product.

This operation, led by the Shom, was carried out in partnership with the Regional Directorate for the Environment, Planning and Housing (DREAL) of Languedoc-Roussillon.

Statement

These data were acquired by airborne lidar during two campaigns conducted between October 5, 2014 and October 31, 2014 and between September 06, 2015 and September 11, 2015.

For both mobilizations, lidar bathymetric data come from a HawkEye 3 sensor in double trap configuration (Chiroptera + Deep Channel).
