Dataset Direct Download Service (WFS): Perimeters of the Natural Risk Prevention Plan (PPRN) of Onard — 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）开发各阶段的边界信息。此类边界的核心特征为：均由官方正式文书确立，并自指定日期起生效。具体包含以下三类边界：— PPRN审批令中规定的法定边界；— 与经批准的RPP所规制范围相对应的风险暴露范围，该经批准的边界属于公用地役权（PM1）；— 研究范围为开展灾害研究的覆盖范畴。
