Simple download service (Atom) of the dataset: Scopes of the Natural Risk Prevention Plan (PPRN) of Mées — Landes (40)

This dataset contains the boundaries at the various stages of the development of the Natural Risk Prevention Plan (NPP). 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 perimeter in the prescription order of a PPRN; — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集涵盖自然风险防范计划（Natural Risk Prevention Plan, NPP）编制各阶段的边界范围。此类边界的核心特征为：均由官方法定文书确立，并自指定日期起生效。 具体包括以下三类边界： — PPRN规定令中划定的法定边界； — 与经核准的RPP所规制范围相对应的风险暴露范围，此类经核准的边界属于公用地役权（PM1）； — 对应灾害研究覆盖范畴的研究范围。
