Map visualisation service (WMS) of the dataset: Perimetres of exposure to risks PPRT of Haute-Vienne — departmental assembly

This dataset contains the boundaries at the different stages of the development of the PPRT. The characteristic of such perimeters is to be the consequence of an official act and to produce their effects from a defined date. This is the following: — prescribed perimeter contained in the prescription order of a PPR (natural or technological); — scope of exposure to risks that corresponds to the perimeter regulated by the approved RPP. This approved perimeter is a public 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（PPRT）不同发展阶段的边界范围。此类边界的核心特征为：系官方法定行为的产物，且自既定日期起生效，具体如下：—— 纳入PPR（PPR）审批令中的法定边界（涵盖自然类与技术类PPR）；—— 对应经核准RPP（RPP）所规制边界的风险暴露范围，该核准边界属于公共役权（适用于PPRT的PM3）；—— 对应开展危险研究所覆盖范围的研究范畴。
