| Abstract: | In this paper the significance of census spatio-temporal database was analyzed,and the spatio-temporal data models were introduced,especially the data models of base state with amendments.Based on the shortage discussion of these data models,a new spatio-temporal data model of base state with amendments was presented and put forward.On consideration of the characteristic of census spatio-temporal data,a scheme to set up the census spatio-temporal database was proposed and an instance was given. |
