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

This approach is led by Shom (Service Hydrographique et Océanographique de la Marine - Oceanography and Hydrography Service of the French Navy) and IGN (French institute for geographical and forestry information), in partnership with French State (DEAL Guadeloupe).

Statement

These data were acquired by airborne lidars during acquisition campaigns conducted from 15 March2019 to 28 March 2019 over the Saint-Martin (french side) and Saint-Barthélemy islands. The DEM (Digital Elevation Model) is accompanied by layers, which add local metadata. Each layer is supported by the same even mesh as the DEM. One layer provides information on the source of most data used to calculate the node, for each node, and the second layer provides information on the evaluation of the distance between the node in question and the different known points used to calculate altitude.

The airborne survey was provided using "Leica HawkEye 4X system (HE4X)".
