摘要
通过分析空间信息服务中的典型空间信息流动增值过程,建立了三种空间信息服务模式:线性传递的链状模式、共建共享的星状模式、基于Web2.0的网状模式。分析了每种模式的空间信息流模型与增值过程,并讨论了适合的空间信息服务应用,以及在Internet上未来会形成的空间信息增值服务网络,展望了空间信息服务的大众化发展方向。结合应用案例,分析了网状服务模式在网格GIS中的应用。
By analyzing the typical geo-spatial information flow process, we propose ward three GISMs： chain model based on linear transfer, star model based on co-construction, and sharing and net model based on Web2.0. The related spatial information applications for every model are also discussed. Moreover, we discuss the geo spatial information value-added services network, which will be formed on the internet in the future, and the development and prospects of GIServices. The development mechanism of geo-spatial information service models is summarized. The application of geo-spatial information net model used in grid based GIS is also discussed.
