Map visualisation service (WMS) of the dataset: Issue of the PPRN field movements of the Clain Valley Vienna Department

In general, the stakes are people, property, activities, elements of cultural or environmental heritage, threatened by hazards and likely to be affected or damaged by it. The sensitivity of an issue to a hazard is called “vulnerability”. This class of object includes all the issues that have been taken into account in the PPR study. An issue is a dated object whose consideration is based on the object of the PPR and its vulnerability to the hazards studied. A PPR issue can therefore be taken into account (or not) depending on the type or types of hazard being treated. These elements form the basis of knowledge of the land use required for the development of the RPP, in or near the study area, at the time of the analysis of the issues. The issue data represent a (fixed and non-exhaustive) photograph of assets and people exposed to hazards at the time of the development of the risk prevention plan. This data is not updated after approval of the RPP. In practice they are no longer used: the stakes are recalculated as needed with up-to-date data sources.
