Dataset Direct Download Service (WFS): Surface issues taken into account in the PPRN flooding of the river Charente in the commune of Brives-sur-Charente 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，受危承险体包括人员、财产、各类生产经营活动、文化或环境遗产要素，此类对象均受灾害威胁，并可能因此遭受影响或损毁。
某一评估对象对灾害的敏感程度，被称为"易损性（vulnerability）"。

本对象类涵盖了风险预防计划（Risk Prevention Plan，简称RPP）研究中所涉及的全部评估对象。评估对象是带时间标记的实体，其是否纳入研究考量，取决于风险预防计划的研究目标，以及该对象针对所研究灾害的易损性。因此，PPR评估对象是否纳入考量，取决于当前所针对的灾害类型。

在评估对象分析阶段，上述要素构成了在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。

本数据集收录的评估对象数据，是风险预防计划编制阶段，受灾害威胁的各类资产与个体的一幅（可呈现且非详尽的）快照。该数据在风险预防计划获批后不再进行更新。实际应用中该数据已不再被直接使用，相关评估对象的信息会根据实际需求，结合最新数据源重新计算生成。
