Map Viewing Service (WMS) of the dataset: Extract from the perimeter of PER Saintes in Charente-Maritime

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); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集涵盖PPRN发展各阶段的界址范围。此类界址的核心特征为：均源自官方法定行为，并自指定日期起生效。具体包含以下三类： — 源自PPR（自然型）法定指令的法定范围； — 风险暴露范围，即经核准的RPP所规制的范围。该经核准的界址属于公用役权范畴（PPRN对应的PM1类型）； — 研究范围，即开展危险源研究的覆盖包络范围。
