Issue on the PPRn of Marquenterre Baie de Somme

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 susceptibility of a hazard issue is called “vulnerability”.This class of #x27; object groups 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 treated. These elements form the basis of knowledge of the soil required for the Â#x27; the development of the PPR, in the zone d’#x27; study or near it, at the date of the issue; analysis of the issues.The data from #x27; issues represent a photograph (fixed and non-exhaustive) of assets and persons exposed to hazards at the time of #x27; development of the risk prevention plan. This data is not updated after PPR approval. In practice they are no longer used: the stakes are recalculated as needed with up-to-date data sources. __Origin__ The boundaries of a restricted zone are represented on the graphical documents of the PPR. Regulatory limits are generally set on natural phenomena, which do not follow cadastral or administrative boundaries. A PPR determines the boundaries of the different restricted zones according to the calculated right-of-way of the hazardous phenomena of the site.Some PPRs may sometimes contain regulations associated with linear or punctual figures (cavities, runoff axis...). The linear and point graphics primitives are to be used in these cases respectively. __Partner organisations__ DDTM Somme __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-d4a0c553-d00b-43d6-9a87-4650c4aa301f) * [COVADIS data standard: Restricted zone of a PPRN](http://geostandards.developpement-durable.gouv.fr/afficherPageStandard.do?jeu=N_ZONE_REG_PPRN_AAAANNNN_S) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/e3921662c0444cfb83684bff07ab432afb91aa8d)
