     Spatiotemporal information is represented using a hybrid approach, which combines explicit representation and implicit representation. History topology explicitly expresses historical relationships among spatiotemporal objects, while descriptors implicitly represent the internal changes of single spatiotemporal object and spatial topological relationships between spatiotemporal objects.
     STORM采用结合显式表达和隐式表达的混合型方法来表示时空信息,其中历史拓扑显式表达时空对象间的历史关联,而描述子隐式表达单个时空对象的内部属性变化以及时空对象间的空间拓扑关系。

The problems of representing spatiotemporal information in spatiotemporal data models are analyzed, and a new spatiotemporal data model named STORM is presented. The model which is based on history topology and descriptors. Spatiotemporal information is represented using a hybrid approach, which combines explicit representation and implicit representation. History topology explicitly expresses historical relationships among spatiotemporal objects, while descriptors implicitly represent the internal changes of single spatiotemporal object and spatial topological relationships between spatiotemporal objects. The STORM model can represent both static semantics and dynamic semantics of spatiotemporal information. It can also represent and query spatiotemporal information using extended relational structures and extended relational algebra.

针对已有时空数据模型在表达时空信息上存在的问题,提出基于一个新的历史拓扑和描述子的时空数据模型STORM。STORM采用结合显式表达和隐式表达的混合型方法来表示时空信息,其中历史拓扑显式表达时空对象间的历史关联,而描述子隐式表达单个时空对象的内部属性变化以及时空对象间的空间拓扑关系。该模型可以同时表达时空信息的静态语义和动态语义,并可通过扩展的关系结构和关系代数操作进行表示和查询。

Transportation information has distinct temporal and spatial distribution characteristics.The need for temporal and spatial information processing in the area of transportation planning promotes the research of GIS temporal and spatial data models.In this paper,based on the spatial vector data structure of ESRI's Geodatabase and the object oriented method,temporal dimension is added to transportation spatial data to express temporal information.Then,through the method of apparently storing events,the historical...

交通信息具有明显的时空分布特性,交通规划对时间和空间信息处理的实际需求促进了对G IS时空数据模型的研究。在G IS软件ESR I's G eodatabase的空间矢量数据结构基础上,采用面向对象的数据管理方法,通过为交通空间数据增加时间维表达时间信息,并通过显式存储事件的方法来建立和分析对象间的历史拓扑关系,从而探讨了对交通对象的几何、语义、时态、拓扑信息进行存储和管理的方法。

>=City Planning information has distinct temporal and spatial distributed characteristics. The need for process of temporal and spatial information in the area of city planning promotes the research of GIS temporal and spatial data modals. In this paper, work is based on the spatial vector data structure of ESRI’s ArcGIS Geodatabase. Using the Object Oriented method, temporal dimension is added to spatial data through adding an exclusive ID to each object. And by using the method of apparently storing events,...
