Simple download service (Atom) of the dataset: Departmental assembly of linear entities at the origin of the risk of a Natural Risk Prevention Plan (PPRN), on the Hautes-Pyrénées

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, or a geologically unstable area.

This layer corresponds to the departmental assembly of the origins of the risk, represented in linear form, on approved PPRNs, the GIS version of which is validated according to the national standard.

风险源（risk origin）指称一类现实世界实体，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，在部分场景下还可通过用于定位该风险实际成因实体的地理对象补充描述。实体的空间位置与对危险现象的认知，可用于界定风险池（risk pools）——即支撑RPP的风险暴露区域。针对NRPPs而言，该实体例如可对应为水道或地质不稳定区域。该图层对应经核准的PPRNs上以线性形式呈现的部门级风险源聚合数据，其地理信息系统（Geographic Information System，简称GIS）版本需按照国家标准完成验证。
