| Abstract: | Four images for ALOS PALSAR of the track 474 before and after Wenchuan earthquake are processed by the software ROI_PAC, and then the tropospheric and ionospheric delay are corrected by ERA??Interim data and NeQuick model. The sedimentation is compared with that derived from five GPS observations, the results show that the mean value of the differences between the sedimentation derived from D??InSAR and that from GPS observations is 0.104 m, which is 0.057 m when the sedimentation derived from D??InSAR which the tropospheric and ionospheric delay are corrected. This illuminates that the accuracy of the sedimentation from D??InSAR is improved after the tropospheric and ionospheric delay are corrected. |
