Abstract :
This paper describes the updated results of the PALSAR CALVAL activity conducted for last three years using the PALSAR calibration archives and the connected ground truth data. The results show that PALSAR has pretty good stabilities on the geometric and radiometric accuracies. Using PALSAR data, change detection on the forest in Indonesia and the polar regions (North Pole region, Antarctica region, and Greenland region) are in progress tracking the change of the sigma-naught and/or the phases.
