Dataset Direct Download Service (WFS): Forest fire hazard zone of the PPRN forest fires, marine erosion and submersion of the Arvert peninsula on Les Mathes in Charente-Maritime

Area exposed to one or more hazards represented on the hazard map used for 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).本类涵盖用于RPP风险分析的灾害地图（hazard map）中所标注的、受一种或多种灾害影响的区域。 灾害地图是灾害研究的成果，该研究旨在评估研究区域内任意点位的各类灾害强度。针对不同灾害类型，需采用专属评估方法，据此可在研究范围内划定若干区域，并依据灾害等级进行分级分区。 对辖区内特定点位分配灾害等级时，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（multi-random PPRNs），灾害地图上的每个分区通常会通过其暴露的各类灾害对应的编码进行标识。 本类包含灾害地图上标注的所有灾害影响区域。受防护结构保护的区域也必须进行标注（可采用专属方式），因为即便设有防护结构，仍可能因结构破损或功能失效而面临灾害风险。 灾害分区可视为经过开发的数据集，其生成过程需整合多源计算、建模或观测得到的灾害数据。本类对象不涵盖这些源数据，相关源数据需遵循另一项用于灾害知识描述的标准。 研究区域内的部分区域被视为“无灾害或灾害可忽略区域”，即经研究确认不存在灾害的区域。此类区域不属于本类对象范畴，无需作为灾害分区进行标注。但对于天然RPP，监管分区可能将部分未受灾害影响的区域划定为规定区域（详见PPR类的定义）。
