Simple download service (Atom) of the dataset: Linear entity at the origin of the PPRMT risk of Loir en Vallée en Sarthe.

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.

风险源表征了一类现实世界实体，该实体的存在即构成潜在风险。此类风险源可通过名称进行标识，在部分场景下还可借助用于定位该风险实际致险实体的地理对象完成表征。依托该实体的位置信息与对危险现象的认知，可定义风险池（risk pools）——即支撑RPP的风险暴露区域。
