PPRN — Entity at the origin of the risk of the SSP of the municipality of CREVECHAMPS (54144)

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. __Origin__ The geometric modeling of ' entity at ' origin of risk depends on the type of risk, the context of the PPR, the nature of the generator and its modeling in the data source or geographical repository from which it originates. For example, a water course may be represented by a polygon or a polyline according to its size and width, an ICPE by a point (if the location of its enclosure is unknown) or by a polygon (especially from the grey area of the PPR). The geometry of this class d'objects is optional when: — this geometry is already carried by an object d'a geographical repository or d' an external data source, to which it is then recommended to refer to the identifier; — it does not exist because the origin of the risk cannot be precisely defined or localised (e.g. earthquakes, avalanches, marine submersions, etc.). However, as it is in practice rare to benefit from stable references to external objects, the geometry of the risk will often result from the duplication of that of l’' object representing l' origin of risk. __Partner organisations__ DDT Meurthe-et-Moselle __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-b6b7b59b-377e-45d2-a7db-29e72d3de189) * [State services in Meurthe-et-Moselle](http://www.meurthe-et-moselle.gouv.fr/Politiques-publiques/Prevention-des-risques/Prevention-des-risques) * [Dynamic Map Consulta'Risks](http://carto.geo-ide.application.developpement-durable.gouv.fr/595/RISQ_CONSULT.map) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/82ad6c8fe7fd7a0df6a9e8e2e99d94207d379f6e)
