We proposed a new geometric correction method, where correlation between simulated irradiance image and ortho-rectified satellite image was used to evaluate geometric transform equation and to optimize its parameters. In this paper, we apply the method to 22 system-corrected Landsat TM images from 1984 to 2000 to check their accuracy and chronological change over 8 study areas. It is shown that there is large distortion in some images processed after 2000. NASDA announced that the usage of nominal orbit information instead of actual orbit information caused this distortion. At present, this type of distortion is mitigated and optimization on two parameters (scene center displacement) seems sufficient for relatively narrow area (18 km × 18 km) as we noted before.
