摘　　要：本文阐述了3DGIS中瓦片数据的基本特征及调度方式,并针对当前海量瓦片数据管理复杂与调度效率低下等问题,探讨了基于紧缩数据结构的海量瓦片数据的管理,分析了瓦片数据紧缩结构模型、检索信息数据结构模型以及基于紧缩结构的瓦片数据的增量更新维护等问题,并通过实验分析了基于紧缩结构的瓦片数据管理与调度的可行性与高效性。This paper described the basic characteristics and the common scheduling method of the tile data in 3DGIS. It firstly analyzed the current problems such as complex management and inefficient scheduling method for the massive tile data, and put forward a management method based on crunched structure. Secondly, it described the models of the tile crunched structure and the retrieve data structure, and studied the issue of the incremental update and maintenance. Finally, experiment proved the feasibility and effi- ciency of the management and scheduling for the massive tile data based on the tile crunched structure.
