Map Viewing Service (WMS) of the dataset: Perimeter of the PPRN flooding by overflow of the Charente River of the commune of Romegoux 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发展各阶段的边界范围。此类边界的核心特征为：其效力源于法定行为，并自指定日期起正式生效。具体包含以下三类：
- 载于PPR（天然）法定指令中的法定范围；
- 与经核准的RPP所规制范围相对应的风险暴露范围，该核准边界属于公共事业地役权（PPRN对应的PM1类型）；
- 研究范围，即开展危险性研究所覆盖的边界范畴。
