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.
