Map Viewing Service (WMS) of the dataset: PPRT Storengy (Linear Issue)

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，受险对象包括受灾害（hazard）威胁并可能因此遭受影响或损毁的人员、资产、活动、文化或环境遗产要素。某一研究议题（issue）对灾害的敏感程度被定义为脆弱性（vulnerability）。本对象类别涵盖了风险预防计划（Risk Prevention Plan，简称RPP）研究中涉及的全部研究议题。研究议题是带有时间戳的对象，其是否被纳入考量取决于风险预防计划（RPP）的目标，以及该议题针对所研究灾害的脆弱性。因此，RPP议题是否被纳入考量，取决于当前所应对的灾害类型。在研究议题分析阶段，上述要素构成了研究区域及其周边区域开展风险预防计划（RPP）所需的土地覆盖认知基础。该类议题数据所呈现的，是风险预防计划（RPP）编制阶段，受灾害威胁的资产与人群的示例性且非穷尽式写照。该类数据在风险预防计划（RPP）获批后不再更新。实际应用中此类数据已不再直接使用：研究议题需结合最新数据源，根据实际需求重新计算生成。
