Abstract: With the spatial data applications to the depth and breadth of expansion, spatial data exist for speed, efficiency and other problems in the organization, storage, update, applications and other aspects. In view of the above problems,based on global subdivision organization theory, combined with the client oriented aggregation service that G/S mode,studied and proposed a space subdivision data storage scheduling service model, and presented the model architecture,data access process,designs the address coding structure and resolution process,forming effective mechanism of space subdivision data organization and management, according to the needs of integration, fast scheduling with data distributed storage and client information aggregation. Finally realized and verified the prototype system, it has certain theory significance and the application value.

Key words: Spatial data, Global subdivision, G/S mode, Facet, Storage scheduling
