Perimeter of the Natural Risk Prevention Plan (NRPP) for Field Movements and Seismic Risks of the Largue and Traubach Valleys in the Upper Rhine

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.本数据集涵盖PPRN发展各阶段的边界范围。此类范围边界的主要特征为：系官方行为所产生的法定结果，且自指定日期起产生法律效力。具体如下： —— 包含于PPR（自然类或技术类）审批决定书内的规定范围； —— 与获批RPP所规制的范围相对应的风险暴露范围，该获批范围边界为公用役权（PPRN对应PM1，PPRT对应PM3）； —— 与危险源研究覆盖范围相一致的研究范畴。
