Dataset Direct Download Service (WFS): Perimeter of the Granville PPRMT

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 following:
— prescribed scope contained in the prescription order of a PPR (natural or technological);
— scope of risk exposure 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在开发各阶段的边界范围。此类边界的核心特征为：均由官方法定行为确立，且自指定日期起产生法律效力。具体包含以下三类：
—— PPR（天然或技术类）处置指令中载明的法定适用范围；
—— 经核准的RPP所规制的风险暴露范围，该核准后的边界为公用役地（PPRN对应PM1，PPRT对应PM3）；
—— 研究包络范围，即开展危害研究时所覆盖的全部区域。
