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 part" comprises data acquired using airborne topo-bathymetric and bathymetric lidar systems as part of phase 1 of the "strategy for homogeneous, recurrent and long-term monitoring of the East Channel - North Sea coastal dynamics". This operation was led by Shom and the Normandy and Hauts-de-France Coast Observation Network (ROL). It was co-financed by the Regional Department for the Environment, Development and Housing of Normandie (DREAL), the Shom, the Seine-Normandy water agency, the Normandy Region, the Artois-Picardy water agency, the Hauts-de-France Region, the European Union within the framework of the European Regional Development Fund (FEDER) and the Parc naturel marin des estuaires picards et de la mer d'Opale.

Statement

These data were acquired by airborne lidars during four acquisition campaigns conducted from 29 September 2016 to 20 October 2016, from 5 May 2017 to 26 June 2017, from 21 August 2017 to 30 September 2017 and from 4 May 2018 to 30 June 2018. The topo-bathymetric data lidar come from a HawkEye 3 sensor in double trap configuration (Chiroptera + Deep Channel).
