A solution for change detection in spatio-temporal database

When modeling spatio-temporal applications, the spatial, temporal but also spatio-temporal aspects like change or motion have to be expressed (Brisaboa, N.R., 1998). For spatio-temporal object (ST-Object), it's necessary to store its correlation link which can be used to track an object's various states over time easily. In this paper, we propose a solution based on spatio-temporal data model to resolve how to detect ST-Object's various states over time and build correlation link and correlation tree into database for different temporal.
