Map visualisation service (WMS) of the dataset: One-off entity causing the risk of PPRN field movements in the Clain Valley Department of Vienna

The origin of 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 areas exposed to the risks that underpin the RPP.

For PPRNs, this entity may, for example, correspond to a river, a geologically unstable area.
