%X The data is the surface deformation rate data of Lanzhou City, Gansu Province from January 2020 to December 2020 obtained by the research team based on sentinel-1a images of orbit lifting and descending and sbas-insar technology. The main fields include annual deformation rate, coherence, vertical accuracy, horizontal accuracy and cumulative displacement. The monitoring accuracy is mm. The monitoring accuracy of surface deformation data is mm, which is suitable for surface deformation monitoring of land surface covered by radar image; Based on envi sarscape, the surface deformation data in SAR coordinate system is finally converted into geographic coordinate system through image clipping, registration, interference processing and geocoding, and stored in shpfile format file.
