| 摘 要： | 时空数据模型的三个基本要素是空间位置、属性和时间．确定研究尺度范围内地理信息基元，合理表达时空关系和模型的层次体系是时空数据模型研究的基本原则．时空数据模型的表达方法主要有序列快照模型、基图修正模型、时空复合立方体模型、基于特征的时空数据模型和图谱数据模型．目前条件下，时空数据模型研究的重要意义在于，扩展传统地理信息系统的功能，实现时态地理信息系统(TGIS)的时序分析与规律预测．

| Abstract: | The temporal-spatial data model (TSDM) consists of three basic elements that are spatial locations, attributes and time. The main fundamentals of TSDM research include identifying the geographic information cell of studied scale, exactly expressing relationships between space and time and the model architecture. The main expressing methods of TSDM have sequent snapshots, base state with amendments, the space-time complex cube, feature-based TSDM and Tupu data model. Nowadays, the important significance of the TSDM study is to expound the functions of classical geographic information system(GIS) and realize time-based analysis and rule prediction of temporal GIS. |
