Dataset Direct Download Service (WFS): Exposure perimeters to risks PPRT of Haute-Vienna — Departmental assembly

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.本数据集涵盖了PPRT开发各阶段的边界信息。此类边界的特征为：均由官方行为所产生，并自指定日期起生效，具体如下： —— 纳入PPR（含自然类与技术类）处方令中的规定范围； —— 与经批准的RPP所规制范围相对应的风险暴露范围，此类经批准的边界属于公用役权（针对PPRT的PM3）； —— 研究范围，即开展危险性研究所覆盖的范畴。
