Map Viewing Service (WMS) of the dataset: Scope of the natural risk prevention plan (PPRN) of the municipality of Merens-LES-VALS

This dataset contains the boundaries according to the stage of development of the PPRN. The characteristic of a perimeter is to be the consequence of an official act and to produce its effects from a specified date. This may include: — 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.本数据集收录了依据PPRN发展阶段划定的各类边界。 此类范围的核心特征为：系官方行为的产物，且自指定日期起产生效力。具体涵盖以下范畴： — PPR（自然或技术类）规定指令中载明的法定范围； — 与获批RPP规制范围相对应的风险暴露范围。该获批范围属于公用役权范畴（PPRN对应PM1，PPRT对应PM3）； — 对应危险源研究覆盖范围的研究范畴。
