Map Viewing Service (WMS) of the dataset: Perimeter of the Barneville PPRL

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PPRN开发全流程各阶段的边界范围。此类边界的核心特征为：由官方行为划定，且自指定日期起生效。具体涵盖以下三类范围：—— 纳入PPR规管指令的规定范围（含天然类与技术类PPR）；—— 风险暴露范围：即经核准RPP所规管的对应范围。该核准边界属于公用设施地役权（PPRN对应PM1，PPRT对应PM3）；—— 研究范围：即开展危险源研究所对应的覆盖包络。
