Dataset Direct Download Service (WFS): Surfacial issues taken into account in the PPRT of the establishment BUTAGAZ in the commune of Douhet 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，风险受体（stakes）指受灾害威胁、并可能因灾害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）研究中涉及的全部相关议题。

议题属于带时间标记的对象，其纳入考量需结合风险预防计划的目标，以及其针对所研究灾害的易损性。因此，是否将某一风险预防计划议题纳入评估范围，需取决于当前应对的灾害类型。

上述要素构成了在议题分析阶段，研究区域内或邻近区域开展风险预防计划编制所需的土地覆盖认知基础。

相关议题数据呈现了风险预防计划编制阶段，暴露于各类灾害中的资产与个体的（可可视化且非穷尽的）现状快照。

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：相关议题可根据需求，依托最新数据源重新计算生成。
