Dataset Direct Download Service (WFS): Perimeter of the Flood Risk Prevention Plan (PRIP) of the Largue Valley in the Haut-Rhin

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 or technological); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs and PM3 for PPRTs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集涵盖PPRN开发各阶段的边界信息。此类边界的核心特征为：系官方法定行为所产生的结果，且自指定生效日期起产生法律效力，具体如下： — 纳入PPR（含自然类与技术类）处置指令中载明的规定适用范围； — 风险暴露范围，对应经核准的RPP所规制的范围。该经核准的边界为公用设施地役权（PPRN对应PM1，PPRT对应PM3）； — 研究范围，即开展危险性研究所覆盖的包络范围。
