Dataset Direct Download Service (WFS): Scope of the PPRT generated by the company TITANOBEL in the municipalities of Moissat, Reignat, Glaine-Montaigut and Ravel (Puy de Dôme)

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:- prescribed perimeter set out in the Prescribing Order of a PPR (natural or technological);- scope of exposure to risks that corresponds to the scope regulated by the approved RPP. This approved perimeter is deemed to be utility easement (PM3 for PPRTs);- scope of study that corresponds to the envelope in which the hazards were studied.本数据集收录了PPRT发展各阶段的各类边界。此类边界的共性特征为：均由官方行为确立，并自指定生效日期起产生法定效力。具体包含以下三类： - 由PPR（自然型或技术型）划定令所载明的法定边界； - 与经批准的RPP所规制范围相一致的风险暴露范围，该核准边界被认定为地役权（PPRT对应的PM3）； - 开展危害研究所覆盖的研究范围边界。
