A Kind of Spatial Data Storage System Based on Global Subdivision Theory for Mobile GIS

In order to better solve unified reference and multiscale framework of storage, organization and service of spatial data, aiming at deficiencies of organization and scheduling methods of spatial data in the mobile GIS service, a kind of new cluster storage management technology based on global subdivision theory is presented in this paper. The main characteristic of this technology is space-based integration storage management. This storage management technology can make data service center provide high-quality spatial location information service more quickly and accurately in real time for mobile GIS users. The study on cluster storage theory based on global subdivision theory will make a solid theoretical foundation for spatial data storage systems in mobile GIS services.
