Linear entity causing the risk of Libercourt’s PPRN

The origin of risk characterises the real-world entity which, by its presence, represents a potential risk. This origin can be characterised by a name and, in some cases, a geographical object l' real entity to #x27; origin of risk. The location of the entity and the knowledge of the dangerous phenomenon are used to define the risk basins, the areas exposed to the risks that form the PPR.For PPRNs, this entity may, for example, correspond to a stream of water, a geologically unstable area. __Origin__ The boundaries of a zone d’#x27;aira are represented on the map of hazards according to the level of l'random. In other words, polygon objects representing zones d'random form a partial coverage of the studied area of which each cover element is a closed polygon in which hazards have the same level of ' intensity. In other words, the criterion for cutting the zones d'random is the level of l'random. __Partner organisations__ DDTM Pas-de-Calais __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-f51acc44-61bb-4a87-a579-e1ed885d036d) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/4c6e87f6c84f0d2c3ab2c8de6df02d427738ca9a)
