Dataset Direct Download Service (WFS): Departmental assembly of the surfacing entities at the origin of the risk of a Natural Risk Prevnetion 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 surface form, on approved PPRNs, the GIS version of which is validated according to the national standard.

风险源（risk origin）是指现实世界中一类实体，该实体的存在本身即构成潜在风险。此类风险源可通过名称进行标识，在部分场景中，还可借助用于定位该风险实际承载实体的地理对象来补充相关标识信息。实体的空间位置与危险现象相关认知，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PPRN上以地表形态呈现的风险源部门级汇总数据，其GIS版本需依据国家标准完成验证。
