Geospatial metadata, data, and services have been widely collected, developed and deployed in recent years. This
flourishing of geospatial resources also added to the problem of geospatial heterogeneity. Interoperability research and
implementation are needed for advancement in potential solutions to integrate and interoperate these widely dispersed
geospatial resources. We design and implement Wuhan Geospatial Information Sharing Platform based on existing
WMS. This platform consists of three components: Web Client, Metadata Catalog, and Data Services. Data Services
provide WMS. All spatial information from different sources has been published as WMS. These WMS have been
described by geospatial metadata compatible with geospatial metadata standard. These geospatial metadata has been
stored in Metadata Catalog. Web Client provides functionalities to access and process WMS described by geospatial
metadata in Metadata Catalog.

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.
