摘要/Abstract

摘要： 从地学中的时空观出发，论述了时空数据模型的研究现状与发展趋势，就几类有代表性的模型原理和特点进行了详细介绍。其次，重点分析了时空数据模型研究过程中急需解决的问题及其根源，认为单纯地在空间维基础上扩展时间维是不能满足时空数据表达需求的。建议从系统理论角度出发，分析、模拟地学现象的基本变化与过程，建立面向对象和过程的、基于时空语义的、符合人类逻辑思维的时空数据模型方法，从而为时态地理信息系统的研究奠定基础。

关键词: 时态地理信息系统, 时空数据模型, 时空数据库

Abstract: On the basis of the spatiotemporal vision in geography, the authors provided a review on spatiotemporal data model (STDM), the stateoftheart and its evolving trends. STDMs currently available are categorized. Definitions and characteristics of typical STDMs are discussed in detail. Meanwhile problems and their causes in STDMs are analyzed particularly. The authors pointed out that it would not satisfy the expression needs of STDMs by simply expanding the existing spatial data models with a temporal dimension. On the contrary, the essential variation and process of geographical phenomena must be analyzed and modeled systematically. An objectoriented and processoriented STDM method that is also spatiotemporal semantic, which matches human logical vision, is the foundation to the study of temporal GIS.

Key words: temporal GIS, spatiotemporal data model, spatiotemporal database
