Map Viewing Service (WMS) of the dataset: Forest fire hazard zone of the PPRN forest fires, marine erosion and submersion of the Arvert peninsula on St-Palais-sur-Mer 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).

用于RPP风险分析的灾害地图上所标注的、暴露于一种或多种灾害的区域。
灾害地图源于灾害研究，该研究的目标是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，其成果是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。对研究区域内某一特定点位的灾害等级进行赋值时，需兼顾危险现象的发生概率与强度等级。
针对多随机PPRN，各区域通常会在灾害地图上通过其受影响的各类灾害对应的编码进行标识。
本类涵盖灾害地图上标注的全部灾害区域。受防护结构保护的区域也必须予以标注（可采用特定方式），因为即便有防护结构，这些区域仍存在受灾害影响的风险——例如防护结构发生破损或防护能力不足的情况。灾害区域可视为经加工整合的数据：其来源于对计算、建模或观测得到的多源灾害数据的综合分析。
此类源数据不属于本类对象的涵盖范畴，相关内容由另一项针对灾害知识的标准进行规范。
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，无需作为灾害区域进行标注。但对于天然RPP，监管区划可将部分未受灾害影响的区域归类为管控要求区域（详见PPR类别的定义）。用于RPP风险分析的灾害地图上所标注的、暴露于一种或多种灾害的区域。
