Simple download service (Atom) of the dataset: Perimeters of the Oeyreluy Natural Risk Prevention Plan (NPP) — 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：均由官方行政行为所确立，且自指定日期起产生法律效力。具体包含以下三类： — PPRN审批指令中规定的法定边界； — 与获批RPP所规制范围相对应的风险暴露范围，该获批边界属于公用事业地役权（PM1）； — 对应灾害研究覆盖包络的研究范畴。
