Optimization Strategy for Building Tile Pyramid of Massive Remote Sensing Images

Abstract

The efficient building of tile pyramids is the basis for achieving efficient visualization of massive remote sensing images and network publishing. With the increasing number of images and amount of data from images, the existing method leads to excessive overall time consumption and low efficiency of the building process due to the poor quality of building algorithms and parallel strategies. In this study, an optimization strategy for building a tile pyramid of massive remote sensing images was proposed. This method comprehensively used the hierarchical blank tiles of remote sensing images and the strategy of multithreading parallel pyramid construction to reorganize the existing tile pyramid construction process. The experimental results showed that the method proposed in this study was less time-consuming and had an obviously improved overall efficiency compared with that of the existing method of building a tile pyramid using massive remote sensing images. Therefore, this method is more advantageous to use than previous methods.
