Dataset Direct Download Service (WFS): Risk — PPRI Perimeters in Loir-and-Cher

This dataset contains the boundaries at the different stages of the development of the RIP. 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 as set out in the PPRI prescription order; — scope of risk exposure that corresponds to the scope regulated by the approved RIP. This approved perimeter is a utility easement (PM1); — scope of study which corresponds to the envelope in which the hazards were studied.本数据集收录了RIP开发各阶段的边界信息。此类边界的核心特征为：均由官方法定行为所生成，并自指定生效日期起产生效力。 具体包含以下三类边界： — 依据PPRI法定指令所载明的规定范围； — 与经核准的RIP所规制的风险暴露范围相一致的风险暴露范围，该经核准的边界为公用役地（utility easement，PM1）； — 研究范围，即开展危险性研究所覆盖的空间范围。
