LITTO3D® Finistère 2014
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).

- Statement
-
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 bathymetric data come from a LADS Mk III sensor.
The topographic and bathymetric data (mixed sensor) in very shallow depths (typically up to 2-3 meters deep, locally more) come from a RIEGL VQ-820-G sensor.
The topographic data come from an ALTM31000AE-IGN sensor
These bathymetric and topographic data were acquired on February 19, 2011, between February 15 and April 28, 2012, and between May 12 and 31, 2012, between February 16 and March 20, 2013, and between May 05 and 07. July 2013.
