摘要:The purpose of this paper is to monitor deformation due to groundwater extraction in urban area using Persistent Scatterer InSAR (PSInSAR) and Photogrammetry. Theoretically, PSInSAR technique allows for millimetre precision ground deformation mapping based on the utilization of long period of interferometric SAR data. One main advantage of PSInSAR method, compared to conventional deformation surveying methods such as levelling and Global Positioning System (GPS), is the coverage of large area. However, PSInSAR method has difficulty in explanation of each single object or detail information of small objects because of current space-borne radar imagery which has approximately 25m spatial resolution. In order to solve this problem, we used aerial photogrammetry method to survey detail information of objects in selected area identified by PSInSAR
