LITTO3D® marine part Iroise Marine Natural Park 2012

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: This operation, led by the Marine Protected Areas Agency (AAMP) and the Marine Natural Park of Iroise (PNMI), was carried out in partnership with the Shom (Hydrographic and Oceanographic Service of the Navy), acting as assistant to the client, particularly in charge of the control and validation of bathymetric data.

Statement

Bathymetric data come from a Hawk Eye Mk II sensor.

Points describe the sea floor and terrain (see note below on topographical data). Long-term anthropic structures (hard constructions such as dikes, wrecks, turrets, lighthouses or piles) will be maintained.

Note on topographical data: A topographical mode is also available for this survey system and can be used to measure abovewater terrain with a higher density (~ 1 point / m²). Only topographical points used to define the land-sea interface were subjected to an exhaustive checking and validation process. In particular, topsoil is not processed (removal of plants and anthropic structures, etc.) on land. On a long-term basis, these topographical data will be replaced with IGN topographical data within the Litto3D® product.
