Dataset Direct Download Service (WFS): 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.

本数据集涵盖了PPRN开发各阶段的边界范围。此类边界的核心特征为：由官方行政行为产生，并自指定日期起生效，具体包含以下三类范围：
—— 天然PPR处置令所载明的法定适用范围；
—— 风险暴露范围，对应经批准的RPP所规制的范围，该核准边界属于公用役权（PPRN对应PM1）；
—— 研究范围，即开展危险性研究所覆盖的空间包络。
