Map Viewing Service (WMS) of the dataset: Perimeter of the PPRN flooding of the Blaise, in Eure-et-Loir (28)

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:- prescribed perimeter set out in the Prescribing Order of a PPR (natural or technological);- scope of exposure to risks 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 that corresponds to the envelope in which the hazards were studied.

本数据集涵盖了PPRN发展不同阶段的边界范围。此类边界的核心特征为：系官方行为所产生的结果，且自指定日期起生效。具体包括以下三类：
1. 由PPR（天然或技术类）的规定令所载明的规定边界；
2. 与获批RPP所规制的范围相对应的风险暴露范围，该获批边界为公用役权（PPRN对应PM1，PPRT对应PM3）；
3. 与灾害研究所涉及的包络范围相对应的研究范围。
