Short summary
Precise leveling and InSAR are the useful geodesic techniques for monitoring the regional land subsidence caused by unlimited groundwater pumping. The main aim of this paper is to integrate the accuracy of precise leveling and the spatial resolution of InSAR with cokriging method for estimating the surface deformation. The results indicate this method is reliable for detecting the land subsidence and the characteristics of different aquifers influence land subsidence.
