Research on building a Geographic Information Services Portal oriented Web Services

Web services technology is emerging as a new approach for providing access to heterogeneous computation resources and integration of distributed scientific applications. Open GIS Consortium (OGC) has constituted a series of standards, guiding creating the Web services to provide or operate geographic information. But it does not show how to integrate these services. While a portal is an application framework based on Web, which provides a single integrated access to applications, and it could integrate distributed information and applications. In this paper, we have tested building a portal oriented Web services to carry out integration and interoperability of geographic information. A framework has been designed based on an open source portal development tool named GridSphere. And some portlets invoking geographic Web services have been created and deployed. The result of the experiment indicates that the solution is feasible, and its operations are simple and convenient.
