Simple download service (Atom) of the dataset: Perimeter of PPRN flooding by overflow of the Charente River of the commune of La Vallée 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.

本数据集收录了PPRN开发各阶段的边界范围。此类边界的核心特征为：其产生源于官方法定行为，且自指定日期起产生法律效力。具体如下：
— 自然型PPR法定审批文书所载的法定划定范围；
— 对应获批RPP所规制的风险暴露范围。此类获批边界属于公共用地役权（PPRN的PM1类型）；
— 研究范围，即开展危险源研究所覆盖的空间域。
