Using Litto3D® Data
The Litto3D® database is distributed as «Open Data» which allows free access and use for everyone.
These recent data have many applications, including risk prevention.
Flooding due to storm Xynthia confirmed the importance of precise mapping for the littoral zones exposed to marine flood risk.
Example application for marine flood risk
Marine flooding occurs when the sea temporarially inundates coastal areas higher than its usual tides. This «hazard» could have socio-economic impacts for the region.
