Abstract: 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.

Key words: spatial data, global subdivision, storage cluster

摘要: 为解决超大规模空间数据有序存储与调度管理的统一基准和多尺度问题, 针对超大规模空间数据的组织、存储与调度管理方法的不足, 提出一套以球面剖分理论为基础, 空间剖分面片与存储单元相映射的空时一体化空间数据存储管理架构。阐述了该剖分集群存储系统的概念、总体研究思路及其架构的核心设计。空间数据剖分集群存储理论的建立将为超大规模空间数据存储系统的建设提供坚实理论基础。
