摘　　要：提出了一种空间数据服务的虚拟化描述方法。针对各类空间数据服务,采用基础描述元素和描述规则描述服务元信息、数据元信息和服务操作信息,并存储为虚拟文件,进而支持用户通过虚拟文件进行空间数据服务的组织管理和综合应用。对天地图、Google Maps、OGC标准服务三类空间数据服务进行集成显示实验,实验结果表明虚拟化描述方法可以有效地实现多源空间数据服务的统一访问与应用。This paper proposed a method that employed virtualization idea to translate spatial data services into logical virtualization resources. The virtualization resources provided users unified access and application of multisource spatial data services. For all kinds of spatial data services, it designed basic elements and description rules to describe service metadata, data metadata and service operations, which were stored as virtual files. The virtual files supported users to implement management and complex application of spatial data services. Experiments on integration of three types of spatial data services were done, including MapWorld, Google Maps and OGC Web services. The results indicate the proposed method is effective to implement unified access and application of multisource spatial data services.
