Surface challenge of a PPR field movement (PPR of Courgeon) in the department of Orne

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 source data sources: DDT61/SACR/PRGC — validity: 30/12/2020一般而言，受险标的系指受灾害威胁、且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，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点。风险点是一类具有时间属性的对象，其是否被纳入考量取决于风险预防计划的目标，以及其对所研究灾害的脆弱性。因此，是否纳入某风险预防计划风险点，需根据所应对的灾害类型而定。 上述要素构成了在风险点分析阶段，研究区域及其周边区域开展风险预防计划编制所需的土地覆盖认知基础。 本风险点数据呈现了风险预防计划编制阶段，受灾害威胁的各类资产与人员的（可呈现但非穷尽）快照。该数据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直接使用：风险点会根据需要，采用最新数据源重新计算：DDT61/SACR/PRGC — 有效期：2020年12月30日。
