Dataset Direct Download Service (WFS): Linear issue of the PPRN 20170003

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 or near the study area, at the time of the analysis of the issues. The data on issues represent a (figible and non-exhaustive) photograph of assets and individuals 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，承险要素（stakes）指受灾害威胁、并可能因此遭受影响或损毁的人员、资产、活动、文化或环境遗产元素。某一对象对灾害的敏感程度被称为“脆弱性（vulnerability）”。 本对象类别涵盖了风险预防计划（Risk Prevention Plan，RPP）研究中涉及的全部研究对象。所谓“研究对象”，是指具有时效性的对象，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脆弱性。因此，是否纳入某一RPP研究对象，需视所针对的灾害类型而定。 在开展研究对象分析阶段，上述要素构成了在研究区域及其周边区域制定RPP所需的土地覆盖认知基础。 该研究对象数据，是风险预防计划制定阶段受灾害威胁的资产与个体的具象化且非穷尽式写照。该数据在RPP获批后不再更新。实际应用中，此类数据已不再直接使用：研究对象需依托最新数据源，按需重新计算生成。
