Dataset Direct Download Service (WFS): Scope of the natural risk prevention plan of Ayse (Haute-Savoie) — approved on 19/11/2001

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.本数据集涵盖PPRN在各开发阶段的边界范围。此类边界的核心特征为：其设立依据法定行为，且自指定日期起产生法律效力。具体包含以下三类范围： — 源自PPR法定审批令的划定范围（涵盖自然类与技术类PPR）； — 风险暴露范围，即经核准的RPP所规制的范围。该核准边界为公用役地：PPRN对应PM1，PPRT对应PM3； — 研究范围，即开展隐患研究的覆盖范围。
