Dataset Direct Download Service (WFS): Perimeter of the PPRMT of Vouvray and Chateau du Loir in Sarthe.

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.

本数据集收录了PPRN在不同开发阶段的边界范围。此类边界的核心特征为：其设立以官方法令为依据，且自指定日期起生效。具体包含以下三类边界：
1. 依据PPR划定令明确的法定边界，涵盖自然类与技术类PPR；
2. 与经批准的RPP所规制范围相对应的风险暴露范围，该经核准的边界属于公用役权范畴，其中PPRN对应PM1，PPRT对应PM3；
3. 与危险性研究所覆盖的包络范围相对应的研究范畴。
