Map Viewing Service (WMS) of the dataset: Linear issues taken into account in the PPRN flooding of the Charente River in the commune of Le Mung en Charente-Maritime

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，风险承险体指受灾害威胁且可能因此遭受影响或破坏的人员、财产、活动、文化遗产或环境遗产要素。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）研究中涉及的全部相关对象。所谓“相关对象”，是指带有时间标记的实体，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，是否纳入某一风险预防计划相关对象，需根据所针对的灾害类型而定。

在开展相关对象分析阶段，上述要素构成了在研究区域及其周边制定风险预防计划所需的土地覆盖认知基础。

相关对象数据展现了风险预防计划制定阶段暴露于灾害中的资产与个体的（有限且非穷尽）快照。该数据在风险预防计划获批后不再更新。实际应用中此类数据已不再被直接使用：相关对象可根据需求结合最新数据源重新计算生成。
