Dataset Direct Download Service (WFS): PPRT Act Appro Surfacic Issue in Ternas

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，风险受体（stakes）指受灾害威胁、并可能遭受灾害影响或损毁的人员、财产、活动、文化或环境遗产要素。某一研究对象对灾害的敏感性被称为“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。研究对象是带有明确时间属性的对象，其是否被纳入考量取决于风险预防计划的目标，以及其针对所研究灾害的脆弱性。因此，风险预防计划相关研究对象是否被纳入评估，取决于当前所针对的一种或多种灾害类型。在研究对象分析阶段，这些要素构成了在研究区域内或邻近区域开展风险预防计划编制所需的土地覆盖认知基础。该数据集收录的研究对象数据，是风险预防计划编制阶段受灾害影响的资产与群体的一份有限且非穷尽的快照。该数据集在风险预防计划获批后不再更新。实际应用中该数据已不再被直接使用：研究人员会根据需求采用最新数据源重新计算研究对象相关信息。
