Perimeter of PPRN on the department of Meuse (55)

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开发各阶段的边界信息。此类边界的核心特征为：均由官方行为产生，并自指定日期起生效。具体包括以下三类： — 自然或技术类PPR指令文书中载明的规定范围； — 与经批准的RPP所规制范围相对应的风险暴露范围。该经核准的边界为公用地役权（PPRN对应PM1，PPRT对应PM3）； — 对应危害研究覆盖范围的研究范畴。
