Abstract

This paper proposes a geospatial web portal for the Tibetan Plateau ecological safety data services based on web services, portal technology and GIS technology. It serves as an online data supporting platform for geospatial data integration, management, submission, publishing and sharing. Its framework presents a three layer architecture consisting of data resource layer, data service layer, data representation layer based on ASP.NET MVC2 and ArcGIS Server 9.3. As employed in the portal implementation, Microsoft Silverlight technology and Bing Map technology, add rich geospatial represent characteristics and interactive performance to the client. The geospatial web portal is an important step in establishing an eco-environment-oriented SDI (Spatial Data Infrastructure) for Tibetan Plateau, which will promote collaborative effort to build, share, and disseminate geospatial information resources for the national ecological safe shelter protection and construction.
