PPRi MOSELOTTE surfacial 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 Risk Prevention Plan (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，风险受体指受危险威胁、并可能因该危险遭受影响或损毁的人员、财产、活动、文化或环境遗产要素。 某一对象针对某一危险的敏感性，被称为"脆弱性（vulnerability）"。本对象类涵盖了风险预防计划（Risk Prevention Plan, RPP）研究中涉及的全部风险要素。 风险要素是一类带时间戳的对象，其是否纳入考量取决于风险预防计划的目标，以及其针对所研究危险的脆弱性。因此，PPR风险要素是否被纳入考量，取决于当前应对的危险类型。在开展风险要素分析时，上述要素构成了研究区域及其邻近区域内制定风险预防计划所需的土地覆被认知基础。 本风险要素数据展现了风险预防计划制定阶段内暴露于危险中的资产与个体的（具代表性且非穷尽的）快照。该数据在风险预防计划获批后不再更新。实际应用中，此类数据已不再使用：风险要素会根据需要，通过最新数据源重新计算生成。
