Dataset Direct Download Service (WFS): Scopes of the Natural Risk Prevention Plan (PPRN) of Candresse — 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控计划（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：系官方行政行为的法定产物，且自指定日期起产生法律效力。具体包含以下三类范畴： — PPRN指令文书中规定的法定边界； — 与获批RPP所规制的风险暴露范围相一致的风险暴露范畴，该获批边界属于公用设施地役权（utility easement，PM1）； — 对应灾害风险研究覆盖范围的研究范畴。
