| Abstract: | Nowadays InSAR has become a focal point of geodetic research for its ability to detect tiny deformation of ground. However, InSAR data may not be accurate enough for application due to the uncertainties in the SAR satellite orbit and the signal disturbances in the atmosphere. Meanwhile the lack of ground feature baffles its application. This paper discusses the feasibility for InSAR associated with georeference of GPS and desived atmosphere parameters to detect deformation at sub millimeter precision the procedure and method by use of GIS for integrating, interpreting and analyzing the results of InSAR and GPS. Finally the prospect on the integration of GPS, InSAR and GIS data for detecting urban land subsidence is given. |
