GridGIS is the application of grid computing technology on GIS field,which aims to realize the spatial information sharing and cooperative service.However,current grid technologies are generally difficult to use,so the development and deployment of Web portals that simplifies usage of grid resources has become popular.Grid-enabled portals can thus serve as simple,single points of entry or gateway to multiple computing resources,providing access to complex grid tools and services.In this paper,we give an overview of GridGIS project and the key role of that GridGIS portal is playing in reaching its goals.Then,we describe the portal and Open Grid Computing Environment (OGCE) portal toolkit.Basing on OGCE and integrated Open Geospatial Consortium (OGC) Web service,we design the architecture of the GridGIS portal.In an open source development environment,we develop and deploy GridGIS portal,which includes authentication module,Grid Port Information Repository (GPIR) portlet,Comprehensive File Management (CFM) portlet,Grid Resource Allocation and Management (GRAM) portlet and Map Viewer portlet.
