Dataset Direct Download Service (WFS): 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PPRN在各开发阶段的边界范围。此类边界的核心特征为：其生成依托官方行政行为，且自指定生效日期起产生法定效力。具体包括以下三类边界： - 由PPR制定令（Prescribing Order of a PPR）划定的法定边界，涵盖自然类与技术类PPR； - 与获批RPP所规制的风险暴露范围相匹配的风险暴露边界；该获批边界属于公用设施地役权（utility easement）范畴，其中PPRN对应PM1，PPRT对应PM3； - 用于开展危险评估的研究范围，即危险分析所覆盖的包络范围。
