Abstract: A compression method of keeping match consistency on remote sensing image is represented. A lot of results of experiments are presented. The results describe the relation between image compression and match. At the same time, conclusion is drawn that for aerial remote sensing image at 25 μm resolution, when the compression ratio is 8:1,match consistency is kept.
