Dataset Direct Download Service (WFS): PPRT — PPRT Perimeter — CAL Ecrouves (54)

This dataset contains the boundaries at the different stages of the development of the PPRT. 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 (PM3 for PPRTs); — scope of study which corresponds to the envelope in which the hazards were studied.

本数据集收录了PPRT发展各阶段的边界信息。此类边界的核心特征为：由官方行为所确立，并自指定日期起生效。具体包括以下三类：
——PPR（天然或技术类）规定指令中载明的法定范围；
——风险暴露范围，与经核准的RPP所规制的范围相一致；该核准边界属于公共地役权（PPRT对应PM3）；
——研究范围，即开展危险评估所覆盖的包络范围。
