With the extending of spatial information system into the distributed network environment, it faces some challenges including the mass data character of the spatial data, the limited band width of current network, the devilishly centralized spatial information management and geographic computing resources, as well as the higher requirements of the spatial information service capability. For overcoming these challenges, this paper puts forward a Geo-Computing oriented self-organized P2P network model, and the structure of the P2P network is designed. For performing spatial analysis tasks, the paper also analyzes the spatial data management on the self-organized P2P network. Finally, the test system, which has simulated the slope analyzing based on the self-organized P2P network, is also presented. Compare with the single server based spatial analysis systems the P2P computing based analysis task performs more efficiently and has a better capability of supporting huge amount of requests from the users.
