应用SOA架构是构建松散耦合地理信息服务组合系统的一个有效途径,本文在深入研究UDDI发布工作流程的基础上,提出了一种扩展UDDI的地理信息服务组合方法,通过研究扩展UDDI的数据结构和功能模块来完成GIS服务的组合过程,为GIS服务组合工作提供了一个有效的解决方案。
SOA provides an effective way for constructing loose - coupled web service composition system. On the basis of studying the generic process of UDDI, the paper proposes a combination method based on extended UDDI of geographic information service by stud- ying the extension of UDDI data structures and functional modules to complete the process of a composition of GIS service, which pro- vides an effective solution to composition of GIS service.
