Simple download service (Atom) of the dataset: Perimeters of the PPRi MEUSE

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.本数据集涵盖PPRN开发各阶段的边界范围。此类边界范围的核心特征为：均由官方行为确立，并自指定日期起生效。具体包括以下三类： ——PPR指令文书中载明的规定范围，涵盖自然型与技术型PPR； ——风险暴露范围，即获批RPP所规制的范围；该获批边界为公用役地，其中PPRN对应PM1，PPRT对应PM3； ——研究范围，即开展危险源研究的覆盖包络范围。
