Dataset Direct Download Service (WFS): Ouanne PPRi (Surface) Issues

Generally speaking, the stakes are people, property, activities, cultural or environmental heritage elements, threatened by a hazard and likely to be affected or damaged by it. The sensitivity of an issue to a hazard is called “vulnerability.”This object class brings together all the issues that have been addressed in the RPP study. An issue is a dated object whose consideration depends on the purpose of the RPP and its vulnerability to the hazards studied. A PPR issue can therefore be considered (or not) depending on the type or types of hazard being addressed. These elements form the basis of knowledge of the land cover necessary for the development of the RPP, in the study area or near it, at the time of the analysis of the issues. The data on the issues represent a photograph (figential and not exhaustive) of the property and of the people exposed to hazards at the time of the development of the risk prevention plan. This data is not updated after approval of the RPP. In practice they are no longer used: the issues are recalculated as necessary with up-to-date data sources.概而言之，风险承险体指受灾害威胁、并可能因此遭受影响或损毁的人员、财产、活动、文化或环境遗产要素。 某一对象对灾害的敏感性被称为‘脆弱性’。 本对象类别涵盖了RPP研究中涉及的全部评估对象。 评估对象为带有时间标记的实体，其是否被纳入考量取决于RPP的目标，以及其对所研究灾害的脆弱性程度。 因此，PPR评估对象是否被纳入考量，取决于当前所针对的灾害类型。 在开展评估对象分析时，上述要素构成了研究区域及其周边区域开展RPP编制所需的土地覆盖认知基础。 本评估对象相关数据，是风险预防规划编制阶段，受灾害影响的财产与人员状况的快照——该快照具有示意性但并非穷尽所有情况。 该数据在RPP获批后不再更新。 实际应用中该数据已不再被直接使用，而是会根据需求，依托最新数据源重新计算得到评估对象相关信息。
