Combination the time characteristics with the spatial features of geographical spatial entity, it is the foundation of dynamic reflection in the world of objective reality. The correlation method of spatial-temporal data is studied with three data types, including point, line, and polygon, by analyzing the changes types and characteristics of multi-temporal spatial data, mining the data correlation information in different periods using the overlay method, and establishing corresponding relationship among objects in different periods with unique identifier. And the experiment is taken based on the land use data of two periods, the correlation is established to the data of two periods, and the simple object tracking query is implemented.
