Map Viewing Service (WMS) of the dataset: Scope of the natural risk prevention plan (PPRN) of the municipality of OUST

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.

本数据集收录依据PPRN发展阶段划定的各类边界。此类边界的核心属性为：系官方行政行为的产物，且自指定日期起产生法律效力。其范畴可涵盖以下三类：
— 天然或技术型PPR审批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，该获批边界属于公用役地（PPRN对应PM1，PPRT对应PM3）；
— 与风险隐患研究覆盖范围相匹配的研究范畴。
