Abstract:Taking the ground subsidence in Taiyuan city as an example,we employ PSInSAR technique with 20 scenes of ENVISAT ASAR images acquired between August 2008 and September 2010.Twodimensional linear regression analysis method is applied to achieve the annual vertical deformation rate map and timeseries deformation maps.It proves PSInSAR results are highly consistent with insitu leveling measurements.
