A new algorithm for fusing thé high-resolution pan with 
multi-spectral low-resolution image was developed. The 
method is base on a atmospheric correction with constructing a 
new PSF matrix and spectral simulation with multi-spectral 
bands. There is an obvious improvement in pan-sharpness and 
extracting geographic features, especially in analyze the tiny 
objects and texture. It is concluded that the new 
pan-sharpening algorithms is a perfect algorithm in fusing the 
high-resolution pan with ms low-resolution image in RS data 
fusion.
