With the development of InSAR technology ,many researchers begin to try to apply InSAR technology on trace deformation monitoring,In some areas of landslides, mining subsidence, city over collecting water surface subsidence, reservoir area surface subsidence and dam deformation monitoring have achieved good results. Now available satellite-borne SAR system can achieve theory monitoring accuracy in surface deformation monitoring , but because of a variety of error factors in reality , it often cant achieve the theory monitoring accuracy.This part is to introduce a way to remove the error factors-water vapor GPS detect method.
