摘要
时态地理信息系统的研究是现代空间信息系统的前景,它有重要的理论和实践的意义。这篇论文根据科学发展和社会需求,分析了时空数据模型当前研究的问题和进展,说明了时态地理信息系统发展的必要性。并提出取其构成特征作为基础的时空模型,和基于传感器机理、时空分析和时空推论的时空模型。所有这些工作会促进时态地理信息系统的新发展。
The study of TGIS is the foreground of current spatial information system; it has important theoretic and practical meaning. This paper demonstrates the necessity of development of TGIS according to the scientific development and social demand, and analyzes the problems and headway of the current study of spatio-temporal data model. And then put forward the spatio-temporal model taken constructing the feature as the basis, spatio-temporal model based on cell mechanism and the spatio-temporal analysis and spatio-temporal reasoning. All of these works can promote the new development of TGIS.
