TLS measurements in the Qinghai-Tibet Engineering Corridor

<p>Deformation monitoring was performance using a TLS with network RTK (Real-Time Kinematic) service provided by national geodetic control network (NGCN) for the China geodetic coordinate system 2000 (CGCS 2000) of permanent reference stations for GNSS (Global Navigation Satellite System).</p> <p>As a supplement to the TLS point cloud data, we prepared the Sentinel-1 deformation data for the freeze-thaw stage in the study area from 2014 to 2020 using Interferometric Synthetic Aperture Radar (InSAR) technology.</p> <p>&nbsp;</p>
