Map Viewing Service (WMS) of the dataset: Linear entity at the origin of Hem’s PPRN risk

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 hazardous phenomenon are used to define the risk pools, the risk-exposed areas that underpin the RPP.For NPPs, this entity may, for example, correspond to a river, a geologically unstable area.

风险源（risk origin）指现实世界中一类实体，其存在本身即构成潜在风险。该风险源可通过名称予以标识，在部分场景下还可借助用于定位该致险实体的地理对象来表征。实体的位置信息与危险现象的相关认知，被用于定义风险池（risk pool）——即支撑RPP的风险暴露区域。以核电厂（Nuclear Power Plants, NPPs）为例，该实体可对应为河流、地质不稳定区域等。
