Natural Risk Prevention Plan (PPRN) RGA of the Alpes de Haute-Provence

Risk Regulatory Zoning Withdrawal of Approved PPRN Argiles, digitised on the parcel. At the departmental level, this layer is not sufficient to have the entire PPRN. A PPRN may consist of one or more different paper plan(s): 1 multi-hazard plan + 1 IF plan (forest fire) + 1 RGA plan (removal of clays) + 1 IVD plan (for other miscellaneous risks). Each paper plan gives rise to the production of a geographical layer, which corresponds to the zoning by hazard type. There can therefore be between 1 and 4 layers that overlap depending on the municipality. It is necessary to download the 4 layers to have all the regulatory information (to be downloaded by the data pack sheet) Structuring in accordance with the COVADIS standard.经批准的黏土类自然风险防治规划（PPRN）的风险监管区划撤销图层，已完成地块层面的数字化处理。 在省级层面，单份该图层无法涵盖完整的PPRN内容。 一份PPRN可由一份或多份不同的纸质规划组成：1份多风险规划、1份IF规划（森林火灾）、1份RGA规划（黏土移除相关风险）以及1份IVD规划（其他各类杂项风险）。 每份纸质规划均对应生成一份地理图层，该图层按照风险类型划分监管区划。 因此根据所属市镇的不同，重叠图层的数量可在1至4幅之间不等。 若需获取全部监管信息，需下载全部4幅图层（可通过数据包表单下载）。 数据结构符合COVADIS标准。
