Dataset Direct Download Service (WFS): Perimeter of the PPRN of the municipality of La Rochelle in Charente-Maritime — 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开发各阶段的边界信息。此类边界的核心特征为：均由官方法定文书确立，并自指定生效日期起产生法律效力，具体如下：——自然属性PPR处置指令中载明的法定规制范围；——与经核准的RPP所规制范围相对应的风险暴露范围，该核准边界属于公用役地（适用于PPRN的PM1）；——对应于危险研究所覆盖空间范围的研究范围。
