摘要: 总结 GIS 互操作的发展阶段及成果,解析传统分布式技术与Web服务技术的对比,提炼 GIS 互操作的 2 种实现模式(基于直接访问模式的互操作方法与基于公共接口访问模式的互操作方法),指出基于 Web 服务的公共接口的互操作方式是目前最为理想的方法,描述这种方法的体系结构,阐述其关键技术,得出Web服务在空间信息、互操作和集成上具有良好的支持和适应性的结论。

Abstract: Through summarizing the achievements and the development stage of GIS interoperability,analyzing the contrast of traditional distributed technique to Web Services technique,abstracting tow modes of GIS interoperability (interoperating mode based on direct accessing and interoperating mode based on common interface),this article pointed out that the ideal method for interoperation was the interoperation mode of common interface based on Web service. Then this article described the structure of the method and expounded the key techniques of the method. At last this article reached the conclusion that Web service was fit for space information,interoperating and integration.

Key words: GIS interoperability, distributed GIS, Web service
