Simple download service (Atom) of the dataset: PPRMT Pontoise (Perimeter)

This dataset contains the boundaries at the different stages of the development of the PPRN. 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 a utility easement (PM1 for PPRNs and PM3 for PPRTs);- scope of study that corresponds to the envelope in which the hazards were studied.本数据集收录了PPRN在各开发阶段的边界范围。此类边界的核心特征为：均由官方文书所确立，并自指定日期起生效。具体包括以下三类： - PPR（自然型或技术型）管控令中载明的法定边界； - 与经核准RPP所规制的风险暴露范围相一致的范围；该经核准边界属于公用役权（PPRN对应PM1，PPRT对应PM3）； - 与危险源研究覆盖范围相一致的研究范围。
