The study on the spatio-temporal model of the moving objects based on LBS

摘要

The establishment of spatio-temporal model of Moving Objects is the foundation of Moving Objects Management and Moving Objects Information Service. Based on the research on Moving Objects and its development, the concept and properties of moving object discussed systemically. A moving object conceptual model called spatio-temporal tube model is presented. The model consists of five major components, I.e. moving points, moving trajectory, space grid, moving events, spatio-temporal tube cell. The model's features of the efficiency dealing with a great lot space-data are described in detail. And the relationships between five elements of the spatio-temporal tube model are also discussed.
