Map Viewing Service (WMS) of the dataset: Ad hoc issues of the PPRN SAONE AVAL

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.

一般而言，风险受体是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程度被称为“易损性”。本对象类别涵盖了风险预防计划（Risk Prevention Plan，RPP）研究中涉及的全部风险受体对象。所谓风险受体对象，是指带有时间戳的研究对象，其是否被纳入考量取决于RPP的研究目标，以及其针对所研究灾害的易损性。RPP研究对象可根据所应对的灾害类型决定是否纳入考量范畴。在开展风险受体对象分析时，上述要素构成了研究区域及其周边区域制定RPP所需的土地覆盖相关知识基础。本批风险受体对象数据，是风险预防计划制定阶段，受灾害影响的财产与人群的示例性且非穷尽式快照。该批数据在RPP获批后不再进行更新。实际应用中该类数据已不再直接使用，而是会根据实际需求，依托最新数据源重新计算风险受体对象相关信息。
