Map Viewing Service (WMS) of the dataset: Linear entity at the origin of the risk of the PPR Flood La Briance avlal Map Viewing Service (WMS) of the dataset: Linear entity at the origin of the risk of the PPR Flood La Briance avlal

The origin of the risk characterises the real-world entity which, through its presence, represents a potential risk. This origin may be characterised by a name and, in some cases, a geographical object locating the actual entity causing the risk. The location of the entity and the knowledge of the dangerous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP.
For NRPPs, this entity may, for example, correspond to a watercourse, a geologically unstable area.
