MODELING AND VISUALIZATION OF SPACE OBJECTS SPATIO-TEMPORAL DATA

In future, 3 Dimensions Geographic information System (3D GIS) should support the temporal dimensions modeling and manage all three components efficiently. It is difficult for current 3D Visualization software to deal with temporal phenomenon. An spatio-temporal data model is proposed in this paper, this data model take geometry-data, space moving data and inside action data of the object into account comprehensively. And accomplish holistic modeling of geometry, action, and moving data of the object. With the increasing of applications need to dispose moving objects, the conventional DBMS can not fit the continuous changing data, moving objects Spatio-temporal Data Model is the key technique of moving objects Spatio-temporal DBMS, thus, moving objects Spatio-temporal data modeling became a popular issue these years.
