Dataset Direct Download Service (WFS): Scope of the plan for the prevention of natural hazards of Marin (Haute-Savoie) — approved on 27/12/2007

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：系官方行政行为的产物，且自指定日期起生效，具体如下： — 纳入自然或技术类PPR的法定指令中的规定范围； — 与经核准的RPP所规制的范围相匹配的风险暴露范围；该经核准的边界属于公用役地范畴（PPRN对应PM1，PPRT对应PM3）； — 对应危险源研究覆盖范围的研究范畴。
