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，受险对象是指受灾害威胁且可能因此遭受影响或损毁的人员、财产、各类活动、文化遗产或环境遗产要素。某一对象针对灾害的敏感程度，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）研究中涉及的全部研究对象。此处的“研究对象”为带有明确时间属性的实体，其是否纳入评估范畴，取决于风险预防计划（RPP）的目标，以及该对象针对所研究灾害的脆弱性。因此，PPR研究对象是否被纳入评估，需根据所应对的灾害类型确定。
上述要素构成了在研究对象分析时点，于研究区域内或其周边开展风险预防计划（RPP）编制所需的土地覆盖认知基础。
本研究对象相关数据，是风险预防计划编制时点下受灾害威胁的资产与个体的（清晰可读但非穷尽）快照。该数据在风险预防计划（RPP）获批后不再更新。实际应用中此类数据已不再直接使用：研究对象需结合最新数据源，按需重新计算生成。
