Dataset Direct Download Service (WFS): Perimeter of PPRN flooding by overflow of the Charente River in the commune of Saintes en 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在各发展阶段的边界范围。此类边界的核心特征为：系官方行为的产物，且自指定日期起产生法律效力。具体包括以下三类：
—— 自然类PPR处置指令中载明的规定范围；
—— 风险暴露范围：与经核准的RPP所规制的范围一致，该核准边界为公用役权（PPRN对应PM1）；
—— 研究范围：即开展危险源研究的覆盖范围。
