在高级时空场景中，例如复杂地理过程的模拟，分析基于表面和体积的复杂对象及时改变其位置和形状是一项中心任务。例如，垃圾填埋场、大规模运动或火山活动的记录需要基于动态几何和拓扑数据库结构的 4D 建模。在本文中，我们介绍了有效处理在 DB4GeO（一种基于服务的地理数据库架构）中实现的地理空间和时间相关数据的概念和实现工作。详细描述了DB4GeO的拓扑和几何数据模型。露天矿的地球科学应用证明了本文开头介绍的概念的有用性。最后，对未来地理数据库工作进行了展望，涉及 DB4GeO 的扩展以及协作 4D 地铁轨道规划背景下的地理对象处理
In advanced spatio-temporal scenarios, such as the simulation of complex geo-processes, the analysis of complex surface- and volume-based objects changing their locations and shapes in time is a central task. For example, the documentation of landfills, mass movements or volcanic activities requires 4D modeling based on dynamic geometric and topological database structures. In this contribution we present our concepts and implementation efforts for the effective handling of geospatial and time-dependent data realized in DB4GeO, a service-based geo-database architecture. The topological and geometric data models of DB4GeO are described in detail. A geoscientific application of an open-pit mine demonstrates the usefulness of the concepts introduced at the beginning of the paper. Finally, an outlook is given on future geo-database work dealing with extensions of DB4GeO and the handling of geo-objects in the context of cooperative 4D metro tracks planning
