Blom’s Italian-French subsidiary participates to the mapping and monitoring of the stretches of the Atlantic and Mediterranean coastline in France. The project has been commissioned by the Finistère Department and the Provence-Alpes-Côtes d’Azur Region.
The project aims to produce a seamless digital terrain model, or DTM, of the French coastline. Blom uses bathymetric and topographic laser scanners to collect accurate data simultaneously from both land and seabed terrain, delivering the response that 21st century decision makers need.
The contract is in the scope of the Litto3D project. Litto3D®, a SHOM* and IGN** programme, aims to produce a seamless digital terrain model of the entire French coast, covering more than 5,500 km length, and will feature at the core of all integrated coastal management projects.
The terrain model and laser data is required for a large number of usage areas, such as for flood risk prevention, pollution, safety at sea or natural disasters, and for regional development of for example ports, tourism and industry. Other examples to usage areas are for public maritime delimitation, change of coastline due to erosion, fauna and flora protection, mineral and living resources concerns, research and scientific studies and military needs such as inshore patrol, search and rescue, amphibious operation and mine warfare.
