Map Viewing Service (WMS) of the dataset: FRASSU Valley PPRI Hazard Area

Area exposed to one or more hazards represented on the hazard map used for risk analysis of FRASSU Valley RIP.
The hazard map is the result of a flood risk study carried out by BRL in 2004 which produced the FRASSU Valley PPRI approved on 09/02/2006.
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.

用于FRASSU Valley RIP风险分析的灾害地图（hazard map）上标注的、受一种或多种灾害影响的区域。
该灾害地图为BRL于2004年开展的洪水风险研究成果，该研究形成了于2006年2月9日获批的FRASSU Valley PPRI文件。
本评估方法针对不同灾害类型定制，可在研究范围内划定一系列区域，形成按灾害等级分级的区划。针对某一地域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强度等级。
本数据集包含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标注（可采用特定标注方式），因为此类区域始终被视为存在灾害风险（如结构破损或防护不足的情形）。
灾害分区可被视为经过加工的数据集，其源于对多源计算、建模或实测灾害数据的综合整合。此类源数据不属于本类对象的范畴，而是由另一项针对灾害认知的标准规范。
