Abstract:
Traditional approaches for modelling spatiotemporal information (snapshots, states and events) are not very efficient and usually not capable of retrieving information based on specific spatiotemporal query. The snapshots modelling technique is the oldest and simplest approach and does not support any spatiotemporal query. The most current approach is the events modelling technique which allows data retrieval using spatiotemporal query. However, deductive capacities are needed for developing a system which is not usually present in traditional databases. One idea is to retain the advantages of each individual traditional approach while combining them to build and develop an efficient spatiotemporal information system.
A case study is presented for building a spatiotemporal information system combining snapshots and events approaches which overcomes some of the problems associated with snapshots and events approaches on their own. This work examines the hybrid (snapshots + events) spatiotemporal modeling technique with generic implementation details.
