Map Viewing Service (WMS) of the dataset: PPRT SMCA (Perimeter)

This dataset contains the boundaries at the different stages of the development of the PPRT. 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 deemed to be utility easement (PM3 for PPRTs);- scope of study that corresponds to the envelope in which the hazards were studied.

本数据集收录了PPRT开发各阶段的边界范围。此类边界的核心特征为：由官方文书确立，且自指定日期起生效。具体包含以下三类：
- 由PPR（自然类或技术类）颁行令中载明的法定边界；
- 与经批准的RPP所规制的风险暴露范围相一致的范畴，该经批准的边界被认定为公用设施地役权（对应PPRT的PM3标准）；
- 对应危险研究覆盖范围的研究范畴。
