Surface entity responsible for the risk of the Canche 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 underpin the PPR.For PPRNs, this entity may, for example, correspond to a watercourse, a geologically unstable area. __Origin__ Geometric modelling depends on the type of l' challenge and its modeling in the data source or geographical repository from which it comes. A stake is usually represented by a polygon, a polyline, or a point with a spatial resolution sufficient to appreciate s' it is concerned by one or more zones of #x27;aira. __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-67fe7e38-2fb9-4b34-9b3b-84b9b781fc17) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/55798206e04269ad529ad0c339a9182948e80b73)
