摘要
在大量调研国外有关文献的基础上，对受到国际ＧＩＳ领域的高度重视的时空一体化数据的地理信息系统ＴＧＩＳ（ＴｅｍｐｏｒａｌＧｅｏｇｒａｐｈｙＩｎｆｏｒｍａｔｉｏｎＳｙｓｔｅｍ）的概念模式、数据模型与功能设计等问题进行了分析，认为建立在时空拓扑结构基础上，具有时空数据管理、查询、时间维数据整合和内插、时序及时空分析工具、可视化操作等功能的ＴＧＩＳ将是未来ＧＩＳ发展的趋势，它将极大地促进ＧＩＳ在应用领域的广度和深度。
Based on references both at home and abroad,the concept model,datamodel and functions of Temporal Geography Information System(TGIS) have beenstudied and evaluated.Developing TGIS which is built up on the base of topologi-cal structure of spatiotemporal data is trend of GIS.The strong TGIS with functionsof space-temporal data management and query,temporal interpolation and aggrega-tion,the tools of time-series and time-space analysis,visualization will promoteGIS to be used more intensively and extensively.
