Spatiotemporal databases deal with changes to spatial objects with time. The Spatiotemporal knowledgediscovery process involves the integration of such database systems with data warehousing, data miningand online-analytical processing technologies. The applications in this domain will process spatial,temporal and attribute data elements and use spatio-temporal relationships among these elements. Theseapplications deal with the evolution of spatial objects and changes in their topological relationships,associations along with time. These advanced database applications require storing, management andprocessing of complex spatiotemporal data. In this paper we consider the classification and modelingrequirements for spatiotemporal applications, System modeling, preprocessing spatiotemporal data,discovering spatiotemporal topological relationships and extension of apriori algorithm for miningspatiotemporal frequent predicates. The design of an appropriate system that can capturespatiotemporal features of datasets is discussed. Prototype implementation of the system is carried out ontop of open source object relational spatial database management system called postgresql and postgis.The algorithms are experimented on historical cadastral datasets which are created using OpenJump.The results that are visualized using OpenJump software are presented. |
