Dataset Direct Download Service (WFS): Perimeter of PPRN flooding by overflow of the median sector the Boutonne of the commune of Vervant in Charente-Maritime

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开发不同阶段的边界范围。此类边界的核心特征为：均由法定行为确立，并自指定日期起生效。具体如下：— 自然类PPR规定指令中载明的法定划定范围；— 与获批RPP规制范围相对应的风险暴露范围；该获批边界属于公共设施地役权（PPRN对应的PM1）；— 对应隐患研究覆盖范围的研究范畴。
