Map Viewing Service (WMS) of the dataset: Perimeter of PPRN flooding by overflow of the Seugne and land movements of the commune of Jonzac 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：均由法定文书所确立，并自指定日期起生效，具体包括以下三类：
— 自然PPR处方指令中载明的法定适用范围；
— 对应经核准RPP所规制的风险暴露范围，该核准边界属于公用役地（PPRN的PM1）；
— 对应危险源研究覆盖范围的研究包络边界。
