Map Viewing Service (WMS) of the dataset: Scope of the natural risk prevention plan (PPRN) of the municipality of LA BASTIDE-DU-SALAT

This dataset contains the boundaries according to the stage of development of the PPRN. The characteristic of a perimeter is to be the consequence of an official act and to produce its effects from a specified date. This may include: — 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.本数据集收录了依据PPRN发展阶段确定的各类边界范围。 该类范围的本质特征为：由官方行为所创设，并自规定日期起产生法律效力。其涵盖范畴如下： —— PPR法定令状中载明的法定范围，涵盖自然型与技术型PPR； —— 与经核准的RPP所规制的风险暴露范围相对应的范围。该经核准的范围属于公用役权（PPRN对应PM1，PPRT对应PM3）； —— 研究范围，即开展危险源研究的覆盖边界。
