Automatic Co‐Registration of Satellite Time Series

In modern remote sensing applications the use of automatic image processing codes is becoming increasingly common. When dealing with satellite time series or multi‐source data, image co‐registration is a time‐consuming, but necessary, pre‐processing step. This study shows how a medium resolution satellite multitemporal dataset can be effectively processed using automatic data processing. Results on real and transformed ASTER data showed that, without human interaction, the automatic ground control points extraction (AGE) technique, developed at Politecnico di Milano, is able to obtain accuracies generally sufficient for practical applications and similar to those reported in other studies.
