TY - Data T1 - Surface deformation data of Heifang platform in Yongjing County, Gansu Province (October 2014 may 2019) A1 - Zeng Runqiang DO - 10.12072/ncdc.LANDSLIDE.db2060.2022 PY - 2022 DA - 2022-04-20 PB - National Cryosphere Desert Data Center AB - The data is the surface deformation rate data of Heifang station in Gansu Province from October 2014 to may 2019 obtained by the research team based on sentinel-1a image 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.
