Map Viewing Service (WMS) of the dataset: NORTANKING PPRT Punctual Issue

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、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）研究中涉及的全部研究对象。研究对象是带有时间标记的对象，其是否纳入考量取决于风险预防计划的目标，以及该对象对应研究所涉灾害的易损性。因此，PPR研究对象是否纳入考量，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制定风险预防计划所需的土地覆盖相关知识基础。本研究对象相关数据，是风险预防计划制定阶段，受灾害威胁的资产与人员的（虽可呈现但并非详尽无遗的）快照式记录。该数据在风险预防计划获批后不再更新。实际应用中该数据也不再被直接复用：研究对象会根据实际需求，使用最新数据源重新计算生成。
