摘要
本文提出了基于web服务、门户技术和GIS技术的青藏高原生态安全数据服务地理空间门户网站。它是地理空间数据集成、管理、提交、发布和共享的在线数据支撑平台。其框架采用基于ASP的数据资源层、数据服务层、数据表示层三层体系结构。. NET MVC2和ArcGIS Server 9.3。在门户实现中采用了微软Silverlight技术和必应地图技术,为客户端增加了丰富的地理空间表示特征和交互性能。地理空间门户网站是构建面向生态环境的青藏高原空间数据基础设施(SDI)的重要举措,将促进地理空间信息资源的共建、共享和传播,为国家生态安全庇护保护和建设服务。
Geospatial web portal for the Tibetan Plateau ecological safety data services
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.
