Map Viewing Service (WMS) of the dataset: Perimeter of the PPR terrain movement in Cournon d’Auvergne (63DDT20070013) prescribes 28/11/2003 — Puy-de-Dôme

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 following: — prescribed scope contained in the prescription order of a PPR (natural or technological); — scope of risk exposure 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 which corresponds to the envelope in which the hazards were studied.本数据集收录了PPRN开发全阶段的边界范围。此类边界具有如下核心属性：其均由官方公文所创设，并自指定日期起生效。具体如下： — 自然型或技术型PPR法定指令中载明的规定范围； — 与获批RPP所规范的范围相对应的风险暴露范围。该获批边界为公用役权（utility easement），其中PPRN对应PM1，PPRT对应PM3； — 对应危险源研究覆盖空间包络的研究范围。
