Map Viewing Service (WMS) of the dataset: Area of hazard of the catchment areas of Valle and Vallon Saint Julien — municipality of Bonifacio

Area exposed to one or more hazards represented on the map of hazards used for risk analysis of the catchment areas of Valle and Vallon Saint Julien in the municipality of Bonifacio. The hazard map is the result of the flood risk study carried out by CEREMA in June 2015 which assessed the flood risk in these watersheds. This study was notified to the town hall on 8/10/2015. The evaluation method is specific to each hazard type. It leads to the delimitation of a set of areas on the study perimeter constituting a zoning 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. All hazard areas shown on the hazard map are included. Areas protected by protective structures must be represented (possibly in a specific way) as they are always considered subject to hazard (case of breakage or inadequacy of the structure). 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. These source data are not concerned by this class of objects but by another standard dealing with the knowledge of hazards.博尼法乔（Bonifacio）市镇范围内，用于瓦莱（Valle）与圣朱利安瓦隆（Vallon Saint Julien）集水区风险分析的灾害地图（hazard map）上所标注的、遭受一种或多种灾害影响的区域。 该灾害地图源自法国环境与公共工程研究中心（CEREMA）于2015年6月开展的针对上述流域洪水风险的研究成果，此项研究已于2015年10月8日通报至市镇政府。 本次评估方法针对不同灾害类型分别制定，通过划定研究范围内的若干区域，形成按灾害等级分级的分区体系。在研究区域内的任意给定点位确定灾害等级时，需综合考量该灾害现象的发生概率及其强度等级。 本数据集涵盖灾害地图上标注的全部灾害影响区域。受防护结构保护的区域也需予以标注（可采用专属方式呈现），因为这类区域始终存在受灾害影响的风险（例如防护结构发生损毁或功能失效的情形）。 灾害影响区域可视为经整合加工的数据集：其生成过程通过整合多源计算、建模或观测所得的灾害数据完成。此类源数据不属于本类对象的管控范畴，而是由另一项针对灾害认知的标准规范进行管理。
