Map Viewing Service (WMS) of the dataset: Area of hazard of the PPRN forest fires of the peninsula of Arvert in the commune of La Tremblade in Charente-Maritime

Area exposed to hazard Forest fires shown on the maps of the “forest fire risk” hazard used for the risk analysis of the RPP. Hazard maps are the result of the study of hazards whose objective is to assess the intensity of each hazard at any point in the study area. 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. For multi-random PPRNs, each zone is usually identified on the hazard maps by a code for each hazard to which it is exposed. All hazard areas represented on the hazard maps 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. Some areas within the study area are considered “no or insignificant hazard zones”. These are the areas where the hazard has been studied and is nil. These areas are not included in the object class and do not have to be represented as hazard zones. However, in the case of natural RPPs, regulatory zoning may classify certain areas not exposed to hazard as prescribing areas (see definition of the PPR class).用于RPP风险分析的"森林火灾风险"灾害地图上标注的受森林火灾灾害影响的区域。 灾害地图是灾害研究的成果，该类研究旨在评估研究区域内任意点位的各类灾害强度。评估方法因灾害类型而异，最终会在研究范围内划定若干区域，形成按灾害等级分级的区划。 在区域内指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及其强度等级。 对于多随机PPRN，灾害地图上的每个区域通常会通过其受影响的各类灾害对应的编码进行标识。 所有在灾害地图上标注的灾害区域均需纳入本数据集。受防护结构保护的区域也必须进行标注（可采用特定方式），因为即便设置了防护结构，仍存在结构破损或防护不足的可能性，此类区域仍被视为处于灾害风险之中。 灾害区域可被视为经加工整合的数据产物，其生成过程需融合多源的计算、建模或观测所得的灾害数据。此类源数据不属于本对象类别的范畴，而是由另一项针对灾害认知的标准进行规范。 研究区域内的部分区域被划定为"无灾害或灾害可忽略区域"，即经专项研究确认不存在灾害风险的区域。此类区域不属于本对象类别，无需作为灾害区域进行标注。但针对自然RPP，监管区划可将部分未受灾害影响的区域归类为规定区域（详见PPR类别的定义）。
