英文摘要	It is an important issue for urban planning to monitor the growth and change information of urban areas using remote sensedimages. The joint use of Landsat TM data and ALOS PALSAR quad-polarization data for extracting change information of urbanareas is investigated. The potential application and the performance of the two data sets are evaluated. The processes including the extraction of features, the dual-threshold EM change detection based on canonical correlation analysis (CCA) and thedetection based on random forest (RF) classification were the major steps. The six bands of Landsat TM data without the thermal band were obtained. The four quad-polarimetric features as R-L circular polarization correlation coefficient, the linear polarization correlation coefficient, the total power (TP) and the cross-polarization isolation (XPI) were extracted from ALOS PALSAR data. And the corresponding differential images were got. The dual-threshold EM change detection and the RF classification were carried out based on these images. Accuracy assessment was done and the results were analyzed and verified.
