For the difficult issues of update of the multi-scale geospatial database,by considering characteristics of temporal data model and multi-scale data model,and incremental multi-scale geographic data update mode,this paper illustrates a multi-scale and multi-temporal spatial database model. The links between multi-scale and multi-temporal data is established by using the data associated table. Through applications,the experiments show that the model is conducive to the update of multi-scale data and the data mining of geographic data.
