摘　　要：地理信息系统(G IS)的迅速发展产生和积累的大量地理空间数据以不同的存储格式存放于不同地点的不同系统和设备中,从而对数据的互操作、共享管理和综合利用产生了极其不利的影响。互联网、分布式计算和空间数据库等新技术的发展给空间数据的共享管理带来了难得的机遇,在分析当前G IS数据互操作相关技术基础上,对面向分布式的多源异构数据互操作机制进行研究,提出了解决方案。With the development of GIS techniques, large numbers of geographic data were produced and accumulated in different systems, equipments and sites with various memorial formats, which resulted in the negative .effects on the data＇s interoperation, sharing management and integrated utilization. New techniques such as internet, distributed computation and spatial data-base brought a scarce opportunity for spatial data sharing management. Based on analyzing GIS data interoperated technique, the present paper studied the mechanism of data interoperation which aimed at the multi-source heterogeneous spatial data and proposed solutions.
