摘要

This paper presents an improved PS-InSAR approach refined from the original one proposed by (Mora et al., 2003), and will analyze the quality and availability of PS-InSAR for determining the subsidence in Taiwan. Some tests are done by using ERS images and some ground truth data in both challenging areas in mid-Taiwan and proper areas in southern Taiwan. In the first areas, the SAR images are acquired before and after the Chi-Chi earthquake. The areas are also covered mostly with dense vegetation. The second areas are located in south Taiwan with continuous subsidence of low velocity and covered with cities and towns. The ground truth data are determined by precise leveling, and are used to evaluate the PS-InSAR results. The precision of the subsidence velocity vectors determined by PS-InSAR in both areas reaches the level of cm/year and mm/year, respectively.
