Dataset Direct Download Service (WFS): PPRMT Gonesse (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（PPRN）演进各阶段的边界信息。此类边界的核心特征为：系官方行为的产物，且自指定日期起产生效力。具体包含以下三类边界：1. 自然类或技术类PPR（PPR）的规定令中明确列明的规定性边界；2. 与经批准的RPP（RPP）所规制的范围相对应的风险暴露范围，该经批准的边界属于公用役权（PPRN对应PM1，PPRT对应PM3）；3. 与危害研究覆盖范围相对应的研究范围。
