Study on System Architecture of Subdivision Storage Cluster for Global Spatial Data

In order to solve the unified reference and multi-scale problems and orderly store and manage massive spatial data,a new storage and management architecture based on global subdivision theory is presented by taking deficiencies of organization and storage methods for global spatial data.The system architecture is integrated with the framework of global subdivision grid(GSG),the computer cluster theory,and the space-temporal integration technology.The main characteristics of this storage technology are the storage based on space and each storage node has an accordingly geospatial meaning.The concepts of global subdivision storage cluster,general design ideal and key design of the system architecture are described.The study on cluster storage theory based on the framework of global subdivision will make a solid theoretical foundation for global spatial data storage systems.
