Building of remote sensing images tile pyramid based on Spark

SHAN Tangjian;ZHONG Hongwei;LI Linhui;WEI Jingqi;GUO Lufang;College of Information and Computer Engineering,Northeast Forestry University;  
With the development of remote sensing means and information acquisition technology,the amount of remote sensing image data increases exponentially. The traditional single-machine centralized storage and retrieval technology has been difficult to meet the needs of efficient storage and fast access of data.On the traditional image pyramid construction method,the paper proposes a memory-based computing engine Spark to construct remote sensing image pyramid. The construction process of the algorithm and the distributed storage structure are given,and the parallel construction of remote sensing image pyramid based on Spark is realized.Experiments showthat compared with the traditional pyramid construction of remote sensing image, the performance and computational efficiency are greatly improved.
