Dataset Direct Download Service (WFS): Ad hoc issues taken into account in the PPRT of the BUTAGAZ establishment 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，风险承险体（stakes）指受某一灾害威胁、并可能因此遭受影响或损毁的人员、财产、活动、文化或环境遗产要素。某一对象针对某一灾害的敏感程度被称为脆弱性（vulnerability）。
该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。研究对象为具有明确时间属性的对象，其是否被纳入评估范畴，取决于RPP的研究目标以及其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，取决于当前所应对的灾害类型。
在开展研究对象分析的阶段，上述要素构成了在研究区域及其周边区域制定RPP所需的土地覆盖相关知识基础。
该类研究对象数据，呈现了风险预防计划制定阶段内暴露于灾害中的资产与个体的（可塑且非穷尽的）快照式记录。该数据在RPP获批后不再进行更新。实际应用中该数据已不再被直接使用：研究人员会根据需求使用最新数据源重新计算相关研究对象。
