Abstract: In order to satisfy the requirement of real-time observation data acquisition,storage,analysis and visualization for moving object and sensor,a new type of GIS,real-time GIS,is needed to develop.A real-time GIS spatiotemporal data model is proposed for dynamic geographic object and dynamic process simulation according to the characteristics of various geographic features and the requirements of storage management in Real-time GIS,the model integrates some related elements-spatiotemporal process,geo-object,event,event type and state.A new GIS has been developed based on the spatiotemporal data model,and this paper takes spatiotemporal data real-time access,storage and visualization of four dynamic geographic objects(moving object,situ object,video object and process simulation object)as an example and verifies the feasibility of the model.
