Abstract: Combing the method of the subjective evaluation and the external evaluation,the thesis studyed deeply on the quality evaluation of satellite remote sensing image data compression.By four tests and analysis,the thesis drives that the subjective evaluation was high external,and was the most basic and valid method on the quality evaluation of satellite remote sensing image data compression now,designing it properly is important.The external evaluation was useful,and PSNR was a good criterion when improving a compression method.The consistency in the subjective evaluation and the extemal evalution,mainly on the parameter of PSNR,XSD and LME.
