With the object of the simplicity of the algorithm

we proposed 2D-RGS（Two Dimensional Image Restoration Method with Gauss-Seidel Algorithm）method of image quality correction for satellite remotely sensed data.Incomparisonwith the restoration method using MTF

the results of this study are as follows:1) It was found that the 2D-RGS method is one of the most superior methodin image quality correction

because everyone can easily carry out the correctionand get the same results.2)The 2D-RGS method can be easily carried out by adjusting only two para-meters called the instrumental function and the dumping factor.CPU time is sho-ter also than correction with MTF.3)Getting efficiently results of applying it to different resolution of satelliteremotely sensed data.
