Simple download service (Atom) of the dataset: Issues (surfacing) of the PPRi de la Loire, Val de Gien

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 the study area or near it, at the time of the analysis of the issues. The data on the issues represent a photograph (figential and not exhaustive) of the property and of the people 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.

概而言之，风险承险体（stakes）指受灾害威胁、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。事件针对灾害的敏感度被称为脆弱性（vulnerability）。本对象类别涵盖了风险预防计划（Risk Prevention Plan，简称RPP）研究中涉及的全部事件。本数据集中的“事件（issue）”为具有时间属性的对象，其是否纳入考量取决于RPP的研究目标，以及其针对所研究灾害的脆弱性。因此，PPR事件是否纳入考量，取决于当前应对的灾害类型。在事件分析阶段，上述要素构成了研究区域及其周边区域内，开展RPP编制所需的土地覆被相关认知基础。本数据集收录的事件数据，是风险预防计划编制阶段内，受灾害影响的资产与人员的示例性（非穷尽式）快照。该数据在RPP获批后不再更新。实际应用中此类数据亦不再直接使用，而是会根据需求，依托最新数据源重新计算相关事件。
