Simple download service (Atom) of the dataset: Issues (surfacing) of the PPRi de la Loire, val d’Orléans (upstream)
收藏资源简介:
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.
一般而言,风险受体指受灾害威胁、并可能因此受到影响或损毁的人员、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即称为“脆弱性”。本对象类集合了风险预防计划(Risk Prevention Plan, RPP)研究中涉及的全部风险点。此处的风险点是一类带时间戳的对象,其是否被纳入考量取决于该RPP的研究目标,以及其针对所研究灾害的脆弱性。因此,是否将某一RPP相关风险点纳入分析,取决于当前所针对的一种或多种灾害类型。在开展风险点分析时,上述要素构成了研究区域及其周边区域内,制定RPP所需的土地覆被认知基础。该风险点数据可被视为风险预防计划编制阶段,受灾害影响的财产与人员状况的示例性且非穷尽性写照。该数据在RPP获批后不会进行更新,实际应用中也不再直接复用:相关风险点会根据实际需求,依托最新数据源重新计算生成。
