Abstract

In order to better solve unified reference and multi-scale 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.
