Simple download service (Atom) of the dataset: Plan for the prevention of natural risks of field movement — Commune de Touffailles — Perimeter — Department of Tarn-et-Garonne

This dataset contains the boundaries at the different stages of the development of the PPRN. 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 scope contained in the prescription order of a PPR (natural or technological);
— scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement (PM1 for PPRNs and PM3 for PPRTs);
— scope of study which corresponds to the envelope in which the hazards were studied.

本数据集收录了PPRN（PPRN）开发全周期各阶段的边界范围。此类边界的核心特征为：均由官方行为产生，且自指定日期起生效。具体包括以下三类：
— 纳入PPR（PPR，自然类或技术类）审批令中的法定范围；
— 与经核准的RPP（RPP）所规制的风险暴露范围相一致的范畴；该核准边界属于公用役地（PPRN对应PM1，PPRT对应PM3）；
— 研究范围：即开展危险分析时所覆盖的完整包络范围。
