Dataset Direct Download Service (WFS): Scope of the Archamps natural risk prevention plan (Haute-Savoie) — approved on 11/04/2018

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开发各阶段的边界范围。此类边界的核心特征为：其源于官方法定行为，并自指定生效日期起产生法定效力。具体包含以下三类范围： —— 载明于PPR规定指令中的规定范围，涵盖自然型与技术型PPR； —— 风险暴露范围，与经核准的RPP所规制的范围一致。该核准边界属于公用役权范畴，其中PPRN对应PM1，PPRT对应PM3； —— 研究范围，即开展危害研究所覆盖的空间包络范围。
