Map Viewing Service (WMS) of the dataset: Surface entity at the origin of the risk of the Canche PPRN

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 basins, the risk-exposed areas that underpin the RPP.For NRPPs, this entity may, for example, correspond to a river, a geologically unstable area.

风险源（risk origin）是指一类现实世界实体，该实体的存在本身即构成潜在风险。该风险源可通过名称进行表征，在部分场景下还可辅以用于定位该风险实际成因实体的地理对象。实体的位置信息与危险现象的相关认知，可用于界定风险盆（risk basin）——即支撑RPP的风险暴露区域（risk-exposed areas）。针对NRPPs而言，此类实体例如可对应为河流、地质不稳定区域。
