Other AbstractThis paper presented an organizational and management algorithm to support fast retrieval and visualization of sphere spatial data, and conducted experiments and analysis with solar wind data. The algorithm mainly includes two parts : sphere space subdivision and storage management strategy. HTM - R hierarchical subdivision method subdivides the sphere into similar grids,and uses grid codes to index data in order to search and locate data quickly. A multi - level data model of sphere was established to support multi - level data display and accelerate the speed of data visualization based on the multi - level nature of subdivision grids. The optimized storage management strategy further improves the speed of data visualization.
