Paper Abstract

Research works and applications of geographical information trend towards global view in space domain and high details in frequency domain. With the rapid development of network communication and distributed computing technology in the past years, it is now technically possible to provide the global high-resolution terrain service through network. Aiming at providing highly detailed terrain service for seamless 3D visualization and analysis over the Internet, this paper discusses the characteristics and bottlenecks of high-performance terrain data service. An extensible multi-pyramid data model is proposed to store and manage spatial data in both client and server sides. Based on this data model, an architectural design of adaptive terrain service is proposed to enhance Quality of Geospatial Information Service (QoGIS). Finally, based upon above studies, a prototype software system is developed for providing real time three-dimensional global terrain visualization service on the network.
