摘要
信息技术的日益发展,使得异构信息资源不断涌现,如何将这些异构信息进行集成成为迫切需要解决的问题。为了解决异构地理空间信息源的共享问题,本文研究了一种面向服务的地理信息共享模式,采用符合OGC标准的WFS、WMS等建立各种标准的服务,使得用户不但可以在网络上方便地调用各种地理空间信息,还可以通过标准的接口将各种标准的数据服务和功能服务与自己的应用系统进行集成,以及将来自不同软件提供的接口的数据进行共享。以武汉市为例,开发并实现了面向服务的地理空间信息公共服务平台,说明了通过标准的服务接口访问服务的方法,该平台在武汉市政务专网上得到了广泛应用。
With the development of information technology and the emergence of heterogeneous information resources,the integration of these information becomes more and more essential.To share the kinds of heterogeneous information,in this paper,a Service-Oriented Architecture （SOA） based Geographical Information Systems （GIS） is proposed,and a prototype system is deployed based on the specification of WFS,and WMS of Open Geospatial Consortium （OGC） standard.Thus that all the departments authorized can access the spatial data within the government intranet,and also these spatial data can be easily integrated into kinds of applications.And the Service Oriented Common Geographical Information Platform is implemented by taking Wuhan as a case study,the method for service interface accessing based on standards is expatiated,and the platform has been widely used by the Wuhan municipal departments.
