摘 要: 随着因特网的迅猛发展与广泛普及,GIS Web服务已成为在企业应用和电子政务中集成地理空间信息与空间分析功能的研究热点。本文介绍一个基于多源GIS Web服务合成的GIS应用,该应用中集成了Intergraph和Demis 公司的WMS兼容服务以及Microsoft公司的MapPoint Web服务,展示了多源 GIS Web服务合成存在的问题以及相应的解决方案。最后探讨CIS Web服务的优点和不足,并提出利用工作流进一步改进GIS Web服务合成的构想。 As the Internet develops rapidly and spreads ubiquitously, GIS Web services become a research hot spot to integrate geospatial information and spatial analysis functions into enterprise applications and egovernments. This paper presents a GIS application based on GIS Web service chaining from multiple sources. The application integrates both WMS-compatible services from Intergraph and Demis, and MapPoint Web services from Microsoft. The development of the GIS application demonstrates the problems and the solutions in GIS Web service chaining. Finally the advantages and disadvantages of GIS Web service are discussed and a future research based on workflow is proposed to improve GIS Web service chaining.
