Surface entity causing the risk of the PPRT Act Appro to Ternas

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 hazardous phenomenon are used to define the risk basins, the areas exposed to the risks that underpin the PPR. In PPRTs, it represents the \#x27; enclosure(s) of the facility(s) classified for the protection of l’' environment (ICPE) at the #x27; origin of the risk analysed and treated by the PPR. In the PPRT methodology, it is described as a grey 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-189b9891-07fd-484f-bffd-15b7f37ef9bb) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/3687a32d65a6349f73459273a6d3d7aa1a42186e)
