Paper Abstract
This work presents the application of PS-InSAR for monitoring large-coverage and dynamical ground subsidence. For
the standard PS-InSAR technique, a large stack of InSAR images is necessary (usually more than 20 images). We
present a method for the extraction of precise subsidence velocity from small InSAR image stacks. Using
ENVISAT/ASAR data within one year duration differential interferograms with multi-master images are generated. A
contour map derived from subsidence product shows a good consistency with leveling measurements. It indicates that
using a small stack of SAR images acquired within a short-time is possible for monitor subsidence with a reasonable
accuracy and reliability.
