Abstract

Abstract: According to the character that InSAR observations are insensitive to deformations of north direction, it is proposed that inferring three dimensional deformations by combing north-south deformation field from GPS interpolation with InSAR results.The proposed method effectively avoids the effects of ignoring north-south deformation information, well improves the accuracy of vertical deformation. Taking the Xi'an city as the research area, combining EnviSat ASAR, ALOS PALSAR and GPS data, inferring absolute deformation rate filed of east-west and vertical directions, contrast of the deformation with 11 leveling points shows that the integration not only be capable of providing three dimensional deformation field but also attain more accurate vertical results compared with ignoring north-south deformation. The result will help acknowledge the Xi'an geological background.
