Design and Implementation of a Geospatial Portal

摘要

Geospatial portals use Web Services to publish available geospatial data and processing services, help applications find them and invoke services or retrieve data. OGC has developed Geospatial Portal Reference Architecture to assist to implement a standards-based geospatially enabled portal application. The Geospatial Portal Reference Architecture is a major for E-Government, National Spatial Data Infrastructures, enterprises and Information Communities. It enables geoprocessing interoperability that makes it possible to exchange heterogeneous geographic information content and share a wide variety of geospatial services over the World Wide Web. In this article, we study the Geospatial Portal Reference Architecture. On the basis of this reference, we design and implement a geospatial portal. This article describes the architecture of this portal, development and deployment of this portal.
