The discussions on GPS and InSAR data integrating and applying in monitoring subsidence and deformation of mines exploitation

The integration of GPS and InSAR data has an important academic meaning.The disadvantages of traditional methods of monitoring deformation and subsidence of mines are described in this paper.The necessity and feasibility of the integration of GPS and INSAR data are also analyzed,and the key problems and technical advantages about the integration are discussed.Some ideas about phase unwrapping algorithm,water vapor and atmospheric delay model,and temporal and spatial models of integration are presented.The characteristics and methods of integration are expounded.Finally,a detailed research scheme is listed.
