Abstract

ASTER has three telescopes corresponding to VNIR, SWIR, and TIR. Unfortunately, there will be a band-to-band misregistration among the data of different telescopes, which is caused by pointing inaccuracy of the telescopes. Knowledge of the pointing has an error of several pixels in VNIR unit. So, the registration techniques are needed to get the registered image. In this study, these techniques are investigated. VNIR data is currently considered as reference. Consequently, registration between VNIR and SWIR and the one between VNIR and TIR is calculated and corrected. The primary candidate of the evaluation of the amount of misregistration is image correlation. It will work for VNIR and SWIR registration. But, another approach seems to be needed for the registration between VNIR and TIR, whose registration may or may not have good correlation.
