Map Viewing Service (WMS) of the dataset: Perimeter of PPRN flooding by overflow of the Charente River in the commune of Rouffiac 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.

本数据集涵盖PPRN发展各阶段的边界信息。此类边界的特征为：系官方行为所产生之结果，且自指定日期起生效，具体如下：
— 自然属性PPR处方指令中载明的法定适用范围；
— 对应经核准RPP所规制范围的风险暴露范围。该经核准的边界属于公用役权 (utility easement)，即PPRN对应的PM1；
— 研究范围，即开展危害研究所覆盖的空间范围。
