Map Viewing Service (WMS) of the dataset: Perimeter of the PPRN of the municipality of St-Georges-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.本数据集收录了PPRN在不同开发阶段的边界范围。此类边界均由法定行为衍生而来，并自指定日期起产生法律效力，具体分为以下三类：—— 自然PPR处置令中载明的法定适用范围；—— 与经核准的RPP所规制范围相对应的风险暴露范围，该经核准的边界属于公用设施地役权（PPRN的PM1类型）；—— 与危险性研究覆盖范围相对应的研究边界。
