Dataset Direct Download Service (WFS): Scope of technological PPR in Héault

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在不同开发阶段的边界信息。此类边界的核心特征为：其由官方行为所产生，并自指定日期起产生效力。具体包含以下三类：1. 由PPR指定令所载明的指定边界（分为自然型或技术型）；2. 与经批准的RPP所规制范围相对应的风险暴露范围，该经批准的边界被认定为公用役权（对应PPRT的PM3）；3. 研究范围，即开展危险源研究的包络范围。
