Simple download service (Atom) of the dataset: Perimeter of the Flood Risk Prevention Plan (PPRI) Water table and seismic over-risk basin Potassium basin of 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.本数据集涵盖了PPRN在不同发展阶段的边界范围。此类边界范围的核心特征为：其源于官方文书，并自指定日期起生效。具体如下： — 自然或技术类PPR的指令文书中载明的规定范围； — 与经核准的RPP所规制范围相对应的风险暴露范围。该核准边界为公用役地（PPRN对应PM1，PPRT对应PM3）； — 对应危害研究覆盖包络的研究范畴。
