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.

本数据集包含PPRN（PPRN）发展不同阶段的边界信息。此类边界的核心特征为：均源自官方法定文书，并自指定生效日期起产生效力，具体分类如下：
— 纳入PPR（PPR）处方令中的法定适用范围（自然范围）；
— 与经批准的RPP（RPP）所规制的范围相对应的风险暴露范围，该经核准的边界为公共地役权（PPRN对应的PM1）；
— 与危险评估覆盖范围相对应的研究边界。
