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).

本数据集涵盖用于RPP风险分析的灾害地图（hazard map）上标注的、暴露于一种或多种灾害的区域。
灾害地图是灾害研究的成果，该类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，据此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。对研究区域内的指定点位的灾害等级进行赋值时，需综合考量该危险现象的发生概率及其强度等级。
针对多随机PPRNs，灾害地图上的每个区域通常会通过其暴露的各类灾害对应的编码进行标识。
所有灾害地图上标注的灾害区域均纳入本数据集。受防护结构保护的区域也必须进行标注（可采用特定标注方式），因为即便设有防护结构，该区域仍可能因结构破损或防护不足而面临灾害风险。
灾害区域可作为经加工的数据集进行描述，此类数据由多源计算、建模或观测得到的灾害数据综合生成。本数据集类别不涵盖这些源数据，相关源数据由另一项涉及灾害认知的标准规范。
研究区域内部分区域被划分为"无灾害或灾害可忽略区域"，即经研究确认无灾害风险的区域。此类区域不属于本数据集范畴，无需作为灾害区域进行标注。但针对天然RPPs，监管区划可能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）。
