Dataset Direct Download Service (WFS): Flooding PPRN hazard zone (Tardoire) in Charente

Surface objects of the hazard areas used for the risk analysis of the natural flood risk prevention plan of the Tardoire en 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.

用于塔杜瓦尔-夏朗德（Tardoire en Charente）自然防洪风险规划风险分析的灾害区域地表要素。
本次灾害研究针对研究区域内任意点位的各类灾害强度进行评估，并据此划定研究范围内的灾害分区，分区等级依据灾害烈度分级。
研究区域内给定点位的灾害等级赋值，需综合考量该危险现象的发生概率及其烈度等级。
针对多随机天然风险防治规划（PPRNs），灾害地图通常会通过编码标识各分区所承受的各类灾害类型。
灾害分区可被视为经开发的数据集，其源自对多源计算、建模或实测灾害数据的综合整合。
