Simple download service (Atom) of the dataset: Flooding PPRN hazard zone (Charente, Montignac to Balzac) in Charente

Surface objects of the hazard areas used for the risk analysis of the natural flood risk prevention plan of the Charente, Montignac to Balzac, 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.

本数据集服务于夏朗德省（Charente）境内蒙蒂尼亚克（Montignac）至巴尔扎克（Balzac）段自然洪水风险预防规划的风险分析，对应其中的危险区域地表要素。

本灾害研究将评估研究区内任意点位的各类危险强度，并依据危险等级对研究范围开展分区划定，分区结果按危险程度分级。

针对辖区内特定点位的危险等级赋值，需综合考量该危险现象的发生概率及其强度等级。

针对多随机自然风险预防计划（PPRNs），灾害危险区划图上的每个分区通常会通过其所暴露的各类危险对应的专属编码进行标识。

危险分区可被视为成熟数据集，其源于对多源计算、建模或实测的灾害危险数据进行综合整合后得到的成果。
