Map Viewing Service (WMS) of the dataset: Perimeter of the PPRN of the municipality of St-Denis-d’Oléron en Charente-Maritime — Forest fires and coastal risks (coastal erosion and marine submersion).

This dataset contains the boundaries at the different stages of the development of the PPRN. The characteristic of these perimeters is to be the consequence of an official act and to produce their effects from a specified date. This is the following: — prescribed scope contained in the prescription order of a PPR (natural); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集涵盖PPRN在不同发展阶段的边界范围。此类边界范围的核心特征为：均由法定行为所确立，且自指定日期起产生法律效力。具体如下： — PPR（自然）审批令中载明的法定划定范围； — 与获批RPP所规制范围对应的风险暴露范围，该获批边界范围属于公用役权（PPRN对应的PM1类型）； — 对应危险源研究覆盖范围的研究范畴。
