Static tile pyramid parallel building method based on MapReduce

The invention provides a static tile pyramid parallel building method based on MapReduce, and belongs to the technical field of remote sensing image processing. The static tile pyramid parallel building method based on the MapReduce aims at fast performing batch remote sensing image parallel processing on the basis of a parallel calculation model of the MapReduce by aiming at the features of remote sensing images. The method is completed by four steps including Map tile processing, creation of Lmax layers of tiles, tile image generation and Reduce tile merging. The invention provides the improved static tile pyramid parallel building method based on the MapReduce, and the combination of fast parallel building of batch remote sensing image tile pyramid and tile pyramid large file generation is realized. Through structures of tile pyramid large files and HBase tile index tables, a fast retrieval model of global tile images is built.
