Map Viewing Service (WMS) of the dataset: Linear issues taken into account in the PPRN flooding of the Charente River in the commune of Rouffiac in 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，受险对象指受致灾因子威胁、并可能因此遭受影响或损毁的人员、资产、活动、文化或环境遗产要素。某一事项针对致灾因子的敏感程度被称为易损性（vulnerability）。
本对象类涵盖了风险预防计划（Risk Prevention Plan，后文简称RPP）研究中涉及的全部风险事项。
风险事项是一类带时间戳的对象，其是否纳入考量取决于RPP的目标，以及其针对所研究致灾因子的易损性。因此，是否纳入某RPP风险事项，需结合当前应对的致灾因子类型而定。

在风险事项分析阶段，上述要素构成了研究区域内及周边开展RPP编制所需的土地覆盖认知基础。

本风险事项数据为风险预防计划编制阶段内，受致灾因子威胁的资产与人员形成了（合格且非穷尽的）快照式记录。该数据在RPP获批后不再进行更新。
实际应用中该数据不再被直接使用：风险事项可根据需要通过最新数据源重新计算生成。
