The Research Progress of Temporal GIS and its Application in Urban Planning

In the process of urban planning, it is necessary to analyze the historical change information to forecast the future development trend and make the scientific spatial decision-making plan, but the existing spatial database is usually static GIS database, which could not provide the historical backtracking function. A solution to this problem is temporal GIS. In this paper, the development of current temporal GIS is analyzed, the spatio-temporal data model construction and the spatio - temporal data query data mining technique is discussed. To put forward a spatio-temporal database based on version control after combining with the existing multi-source database of urban planning, comprehensively analyzing of the difficulty of building different temporal GIS platform is the compromise scheme of current urban planning database construction, and the spatio-temporal database system which could support spatial and temporal query, mining and forecasting, and posses a rich event definition to reflect the continuous changes of urban spatial and temporal data is needed faced with the visualization requirement of "One Picture" in Urban Planning.
