Dataset Direct Download Service (WFS): Perimeter of PPRN flooding by overflow of the Charente river of the commune of Crazannes 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开发各阶段的边界信息。此类边界的核心特征为：均由官方行为创设，并自指定日期起产生效力。具体如下：
—— 法定适用范围：载于PPR法定文书中的自然型法定范围；
—— 风险暴露范围：与经核准的RPP所规制的范围一致，该核准边界属于公用役权（PPRN对应PM1项）；
—— 研究范围：即开展危险源研究所覆盖的边界区间。
