Simple download service (Atom) of the dataset: 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：均由官方行为产生，并自指定日期起生效。具体包括以下三类： — 天然PPR法定指令所载的规定范围； — 对应获批RPP所规制范围的风险暴露范围，该获批边界为公共地役权（PPRN对应的PM1）； — 与危险源研究所覆盖范围一致的研究范围。
