Litto3D Saint-Pierre-et-Miquelon 2023

Litto3D provides 3D, continuous sea-land description of French coastal areas. Data is acquired by airborne topo-bathymetric LiDARs. Litto3D products come in 3D point clouds and digital terrain models formats.

Litto3D Saint-Pierre-and-Miquelon product covers land area of the islands as well as bathymetry down to approx. 20m.

Presentation form: Digital map

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 operation was carried under Shom's technical leadership, with assistance from IGN (French mapping agency) and financial support from the French Ministry of Environnement
