Simple download service (Atom) of the dataset: Perimeter of the Lawe PPRN

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. It’s about the
— prescribed scope contained in the prescription order for 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 which corresponds to the envelope in which the hazards were studied

本数据集收录了PPRN发展各阶段的边界信息。此类边界的核心特征为：系官方行为所产生的法律效果，且自指定日期起正式生效。本数据集涉及以下三类范围：一、针对PPR（天然或技术类）的审批令中载明的规定范围；二、与经批准的RPP所规制的风险暴露范围相一致的风险暴露范围；该经批准的边界即为地役权（PPRN对应PM1，PPRT对应PM3）；三、研究范围，即开展危害研究所覆盖的空间范围。
