Abstract:

How to efficiently organize and manage growing massive multi-sourcespace science data and enhance the availability and usability of data is a key technical problem to solve. Based on a full analysis of existing space science data management technologies and data characteristics, we propose an effective system architecture. Spatial relational database and distributed database technology are studied and utilized to achieve efficient storage, retrieval and positioning of massive heterogeneous data.The key technologies of levels of details display, 3D data clipping, and parallel loading via multi-thread based on 3D digital earth are studied so as to improve the efficiency of integrated visualization and application for space science data. Finally, we design and integrate a multi-source space science data visualized organization and management system. Practical engineering application results show the rationality and validity of the system design.

Key words: space science data, three-dimensional earth, data organization, visualized management
