Map Viewing Service (WMS) 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.本数据集收录自然风险防范计划（Natural Risk Prevention Plan, NPP）编制全流程各阶段的边界范围。此类边界均由官方行政行为产生，并自指定日期起正式生效。 具体涵盖以下三类边界： — PPRN审批指令中载明的规定边界； — 与已获批RPP所规制的风险暴露范围相对应的边界，该获批边界属于公用役权（PM1）； — 对应于危害研究覆盖范围包络的研究边界。
