摘要
总结了TGIS中的时空数据模型的发展历史,分析了序列快照模型、基态修正模型、时空复合模型、时空立方体模型、非一范式模型和对象关系模型等几种典型的时空数据模型的特点,提出了建立基于栅格数据的对象关系时空数据模型的必要性。
The paper summerized the history of spatio-temporal data model in Temporal Geographic Information System(TGIS),and also analyzed the characteristics of some typical spatio-temporal data models, such as Sequent Snapshots Model, Base State with Amendments Model, Space-Time Composite Model, Space-Time Cube Model, Not First Normal Form(N1NF) Model and Object-Oriented Spatio-Temporal Model. At the end of the paper, the authors presented the necessity of designing object-rational spatio-temporal data model with raster data.
