摘要：

How to describe 3D moving objects motion model of good adaptability, how to present and store moving objects data in database and realize the self-adaptive dynamic visualization of 3D moving objects with positioning and communication information, are the key problems on data organization and management of 3D moving objects. The information about 3D moving objects are references with the location and time, including the real time geographic information. This paper proposes a new method of multi-scale data organization and management of 3D moving objects based on GIS. The 3D-terrain is rendered with triangle subdivision bi-tree data structure and LOD, which are easy to realize the rapid visualization for 3D moving objects. The experiments show that the propose method is suitable to 3D moving objects in large-scale complex virtual environments.
