Simple download service (Atom) of the dataset: Perimeter of PPRN flooding by overflow of the Charente river of the commune of Chérac

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。此类边界的共性特征为：均由法定文书确立，并自指定日期起生效。具体涵盖以下三类边界：
—— PPR（PPR）法定指令中载明的自然型规定适用范围；
—— 风险暴露范围：即经核准的RPP（RPP）所规制的范围，该核准边界属于公用役权范畴，对应PPRN的PM1（PM1）；
—— 研究范围：即开展隐患研究的覆盖区域。
