In recent years, China's real estate market is developing rapidly.The changing of land and house property right becomes more and more frequent. It demands us to grasp lots of nowadays , true and accurate geographical positioning comprehensive information.So that real estate archives data should be instantly and quickly queried and can be comprehensively analyzed and forecasted. However,there exists a lot of real estate transactions which require the real estate archives to satisfy the requirement of the historical state can be preserved, restored and tracked.It can provides a reliable proof for the real estate development, forecasting, planning policy, urban management, engineering and design. Strengthening research on the real estate archives management theory and technology based on GIS,exploring how to build a model is very important which reflects dynamic the spatio-temporal changes of the real estate archives,can provide a complete description of each moment of the housing situation, can record the true housing historical information,can preserve, restore, track and forecast real estate historical state.This paper researched the real estate archives management based on GIS. First, this paper studied the history of spatial-temporal data model and its application on the real estate, did some research of the current several major spatio-temporal data model.After studied of the real estate archives, the hidden rules of spatio-temporal data change were revealed and expressed. Second, this paper defined the real estate archives spatio-temporal objects with the object-oriented view, designed the real estate archives spatio-temporal data model.It organized the spatio-temporal data model by aggregated and composited the real estate archives' spatio-temporal objects.Designed the spatio-temporal data database, Used the three separated database technology realized data updating and maintenance. Finally,this paper realized the real estate archives' spatio-temporal data query and analysis, validated this model.The main research results of this paper included the following five aspects :1,Revealed and expressed the rules of spatial and temporal changes of the real estate archives;2,Defined the real estate archives' spatio-temporal objects. Built an object-oriented real estate archives spatio-temporal data model which can expressed various of spatio-temporal changes of real estate archives effectively.3,Designed the spatio-temporal database, used the three databases Separation Technology provided a data update way can solved the massive data efficient problem.4,Implemented the real estate archives spatio-temporal query and spatio-temporal analysis and the real estate archives historical graphics backtrack. 5,Implemented the real estate archives' visualization.
