The ASTER (advanced spaceborne thermal emission radiometer) includes three telescopes sensitive to different wavelengths. As the telescopes are capable of changing sight directions, some band to band registration technique among images with different spectrum characteristics will be necessary. In this study, we propose a new registration method using image matching to deal with these problems and experimental results for airborne images are shown. This method is based on chip matching technique and consists of three processes. The experimental results were better than the results of the conventional method. The algorithm will be included to the ASTER level 1 data processing and the requirement that the band-to-band registration error should be less than 0.3 pixel will be achieved.
