摘要

空间数据服务越来越多地出现在互联网上，包括OGC(开放地理空间联盟)网络服务和专有地图服务(例如谷歌Maps)。集成这些异构服务以生成复杂应用程序所需的信息是有意义的。为了实现集成，需要对服务进行统一描述。在本研究中，采用云计算中的虚拟化思想，通过将物理资源转换为逻辑资源来隐藏接口差异。相应地，提出了一种基于资源虚拟化的空间数据服务集成描述方法。最后，本文利用本文提出的方法实现了一个虚拟文件系统。通过运行虚拟文件，包括MapWorld、谷歌Maps和OGC标准服务，对多源空间数据服务进行了覆盖实验。实验结果验证了所提描述方法的有效性。

A Description Method for Spatial Data Service Integration by Resources Virtualization

Spatial data services are increasingly available on the Internet, including OGC (Open Geospatial Consortium) web services and proprietary mapping services (e.g. Google Maps). It makes sense to integrate these heterogeneous services to produce the information demanded in complex applications. For integration, unified descriptions of services are required. In this study, the virtualization idea used in cloud computing is employed to conceal interface differences by translating physical resources into logical resources. Correspondingly a description method for spatial data service integration by resources virtualization is presented. Finally, this article implements a virtual file system using the proposed method. Experiments were conducted to overlay multi-source spatial data services by operating virtual files, including MapWorld, Google Maps and OGC standard services. The effectiveness of the proposed description method is verified by experimental results.
