Liu Ren · 2001
By analyzing the limitations of several typical spatial temporal data models, the extension methods of improvement were presented for spatial temporal data model of base state with amendments in the paper.It was suggested that fast index of time segments, index factors of variable granularity, present state sub database, flow track sub database and historical sub database should be used to describe the spatial temporal process and relationship in base state with amendments.A commercial land registration management system was developed with the given methods.
