Litto3D® - Brittany 2018-2021

Litto3D® is a unique and continuous land-sea database which provide 3D models of french coastal areas. Surveys are carried out by airborne lidar bathymetry over the sea side and airborne lidar topography over the land up to 2km inland. Litto3D® digital models are available in two formats: a set of 3D points and a digital terrain model.

The product "Litto3D® - Brittany 2018-2021" covers the coastline and islands of Côtes d'Armor, Ille-et-Vilaine and Morbihan departments.

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" are supplemented by inland elevations data from IGN RGE Alti database. This operation was led by Shom and IGN (French institute for geographical and forestry information) in partnership with French State, the Brittany Region and the Regional Department for the Environment, Development and Housing of Brittany (DREAL) with 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 4 may to 30 June 2018, from 3 May to 1 July 2019, from 26 August to 26 October 2019, from 3 February to 13 March 2020 and from 4 May to 2 July 2021. The topo-bathymetric data lidar come from a HawkEye 3 sensor in double trap configuration (Chiroptera + Deep Channel).
