Applications of GPS/InSAR integration in monitoring of land subsidence

This paper analysis the advantage and disadvantage of the applications in monitoring land subsidence between GPS and InSAR technology. GPS/InSAR integration can enhance the ability of measuring land deformation in both temporal and spatial resolution, this is very useful to monitor land subsidence. This paper demonstrates the theory and method of GPS/InSAR integration, and through a simple example to prove the feasibility of GPS/InSAR integration, and then discusses the prospects of GPS/InSAR.
