Map Viewing Service (WMS) of the dataset: Perimeter of PPRN flooding by overflow of the Boutonne on the commune of Nouillers 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（PPRN）开发各阶段的边界范围。此类边界范围的核心特征为：均由官方公文所确立，并自指定生效日期起产生法律效力。具体包含以下三类：
—— 自然类PPR（PPR）指令文书中载明的法定适用范围；
—— 与获批RPP（RPP）所规制范围相对应的风险暴露范围，该获批边界为公共事业地役权（PPRN专用PM1）；
—— 对应于危险源研究覆盖域的研究范围。
