Dataset Direct Download Service (WFS): Flooding PPRN hazard zone (Aume and Couture) in Charente

Surface objects of hazard areas used for risk analysis of the natural risk prevention plan for the Aume and Couture in Charente.
The study of the hazards assesses the intensity of each hazard at any point in the study area and leads to the delimitation of a zoning on the study perimeter, which is graduated according to the level of the hazard. The allocation of a hazard level at a given point in the territory takes into account the probability of occurrence of the dangerous phenomenon and its degree of intensity.
For multi-random PPRNs, each zone is usually identified on the hazard map by a code for each hazard to which it is exposed.
Hazard zones can be described as developed data to the extent that they result from a synthesis using multiple sources of calculated, modelled or observed hazard data.

夏朗德省（Charente）欧姆河与库图尔河区域自然风险防治规划风险分析所用的危险区域地表要素。
本灾害研究针对研究区域内任意点位的各类灾害强度开展评估，据此对研究范围开展分区划定，分区等级依据灾害风险水平划分。对区域内特定点位进行灾害等级赋值时，需综合考量该危险现象的发生概率与强度等级。
针对多随机自然风险预防计划（PPRN），危险地图上的每个分区通常会通过其所面临的各类灾害对应编码进行标识。
危险区域可被视为经加工完善的数据集，其生成依托多源计算、建模或实测灾害数据的综合整合。
