Dataset Direct Download Service (WFS): Perimeter of the Grand Lucé PPRMT 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开发各阶段的边界范围信息。此类边界的核心特征为：系法定官方行为的产物，且自指定日期起产生法律效力。具体包含以下三类边界：
- 由PPR（自然类或技术类）的划定令所载明的法定划定边界；
- 与经核准的RPP所规制的风险暴露范围相一致的风险暴露范围，该核准边界为公用地役区（PPRN对应PM1，PPRT对应PM3）；
- 与危险源研究覆盖范围相对应的研究范围。
