    • Abstract
  • 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.
