ZHU Qian1,LI Xia1,LIU Lingling2(1.School of Earth Science and Resources,Chang'an University,Xi'an 710054,China; 2.Shanxi Administration of Surveying,Mapping and Geoinformation,Xi'an 710054,China)  
In order to find suitable multispectral images and fusion methods for the pan-sharpening of TH-1 panchromatic images,IHS,Wavelet,PCA,P+XS,Brovey five transformation methods were used to separately fuse TH-1 PAN with TH-1 MS,TM MS and ETM MS,and the fusion results were assessed from visual and quantitative aspects.Results show that TH-1 PAN and TH-1 MS fusion combination have the best quality;Wavelet transformation can keep the best spectral information,P+XS and Wavelet transformation can keep the best spatial information,and Brovey and IHS can get the best overall quality.
