New Aquitaine: Scopes of Natural Risk Prevention Plans (PPRN) Avalanche (surfacic)

This dataset contains the perimeters of delimitation at the different stages of l' elaboration of the Avalanche PPRNs (surface objects) of the Nouvelle-Aquitaine region. The perimeters have the characteristic of being the consequence of an official act and to produce their effects as of &a defined date. Depending on the PPR, this perimeter may be of different type: — prescribed perimeter set out in the prescribing order of n°#x27; a PPR (natural or technological); — perimeter d' exposure to risks that corresponds to the perimeter regulated by the approved PPR. This approved perimeter is deemed to be servitude of public utility; — perimeter d' study corresponding to #x27; envelope in which hazards have been studied. NOTE: Detailed metadata by PPRn is available from DDT/M. Some PPRn may be in the process of revision. The data are provided for informational purposes and have no regulatory value. GIS data for PPRs are not exhaustive. __Origin__ The perimeter of a prescribed PPR is usually provided in the prefect’s prescription order. The perimeter d' exposure to risks — or regulated perimeter — corresponds to the \#x27; geometric aggregation of l' all the restricted zones listed in the same PPR. The perimeter of the study corresponds to the envelope in which the hazards were studied. This JDD was created on the perimeter of the Nouvelle-Aquitaine region during the construction of ' harmonisation of heritage, it is produced from l' assembling data from the 3 former regions Aquitaine, Limousin and Poitou-Charentes. __Partner organisations__ DREAL Nouvelle-Aquitaine __Links annexes__ * [basketDownloadFrontalParametrage](https://catalogue.sigena.fr/geosource/panierDownloadFrontalParametrage?LAYERIDTS=3933578) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/c457f785329df55cbde8f3f8018e1616bf29a608)
