Map Viewing Service (WMS) of the dataset: Scope of the natural risk prevention plan (PPRN) of the municipality of SAINT-JEAN-DU-FALGA

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:

— 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.

本数据集包含依据PPRN发展阶段划定的各类边界。
