【摘要】 本文分析GIS在功能和数据共享上存在的问题及不足和新型分布式Web服务技术,研究了当前的Web服务技术原理和特点,根据GIS发展的需求,探讨了Web服务技术在GIS数据和功能共享方面的优势,提出了一种基于Web服务GIS的模型体系结构,并将模型应用于具体实例开发过程中,验证模型的可行性。本模型采用C/S开发模式,在结构上分为两大部分:客户端应用和服务器端GIS服务,双方以HTTP/XML进行通信,通过GIS服务的定义、发布、发现、绑定、调用等机制实现服务的松散耦合的集成,为互联网上GIS数据和功能共享提供了一种可借鉴的模型结构。更多还原

【Abstract】 This paper analyses the problems and deficiencies of fuctions and data shared in GIS and new model distributed Web Services technology, then researches theories and characteristics of Web Services technology. According to needs of GIS development,after discussing the advantages of Web Services technology on GIS fuctions and GIS data shared,this paper brings forward a GIS model framework based on Web Services and applies it to a special instance development process successfully which proves the feasibility of the model designed.This model adopts mode of C/S and is divided into two parts:applications in client and GIS services in server which communicate with each other in http/xml. It accomplishes an application integration frame of loose coupling through such mechanisms as GIS service definition, service advertising, service discovery, service binding and service invocation etc .This model frame provides a new reference one for GIS fuctions and GIS data shared in the net.
