Dataset Direct Download Service (WFS): Perimeter of the PPRN flooding and land movements in the commune of St-Savinien 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开发各阶段的边界范围。此类边界的核心特征为：均系官方行为的产物，并自指定日期起产生法律效力。具体包括以下三类：——自然类PPR法定指令所包含的规定范围；——经批准的RPP所规制的风险暴露范围，该获批边界为公用设施地役权（PPRN的PM1类型）；——危险源研究范围，即开展危险源研究的覆盖包络范围。
