Simple download service (Atom) of the dataset: Perimeter of the PPRN of the municipality of Le Bois-beach in Charente-Maritime — Coastal risks, coastal erosion, marine submersion and forest fire.

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开发各阶段的边界范围。此类边界的核心特征为源自官方行政行为，并自指定生效日期起产生相应效力，具体如下： — 天然PPR处方令中载明的法定适用范围； — 与经核准RPP所规制的范围相对应的风险暴露范围，该经核准的边界范围属于公用役地范畴，对应PPRN的PM1； — 研究范围，即开展危害研究所覆盖的空间范围。
