Map Viewing Service (WMS) of the dataset: Perimeter of PPRT of the establishment Picoty/SDLP (Sté du Dépôt de La Pallice) in the municipality of La Rochelle in Charente-Maritime

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 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 (PM3 for PPRTs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集收录了PPRT各开发阶段的边界范围。此类边界的核心特征为：均由官方行为所确立，且自指定日期起生效。具体包括以下三类：——PPR审批令中载明的规定范围（涵盖自然类与技术类两类）；——与获批RPP所规制范围相对应的风险暴露(risk exposure)范围；该获批边界属于公共役权(utility easement)（针对PPRT的PM3）；——对应危险源(hazard)研究包络范围的研究范畴。
