Map Viewing Service (WMS) of the dataset: PPRN — Entity at the origin of the risk of dissolution of salt in the municipality of Sommerviller (54509)

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.风险源即指那些其存在本身便构成潜在风险的现实世界实体。该风险源可通过名称进行表征，在部分场景下还可借助地理标识物来定位该实际致险实体。实体的位置与危险现象的相关认知，可用于定义风险池（risk pools）——即支撑RPP运作的风险暴露区域。
