TLS and InSAR Deformation Measurements for the Qinghai-Tibet Engineering Corridor

Deformation monitoring data for the Qinghai-Tibet Engineering Corridor, collected using Terrestrial Laser Scanning (TLS) and Interferometric Synthetic Aperture Radar (InSAR) technology. The dataset was prepared by Lihui Luo of the Chinese Academy of Sciences and includes Sentinel-1 data covering the freeze-thaw stage from 2014 to 2020.

Use Cases

• Monitoring ground deformation and subsidence based on TLS point cloud data.
• Analyzing seasonal freeze-thaw cycles and their impact on terrain based on Sentinel-1 InSAR data from 2014-2020.
• Validating geodetic models for infrastructure corridors based on combined TLS and GNSS network RTK measurements.

Strengths

• Includes data from two complementary remote sensing technologies: TLS and InSAR.
• Covers a multi-year time series from 2014 to 2020 for the freeze-thaw stage.
• Geodetic control is tied to the national CGCS 2000 coordinate system via the NGCN network.

Limitations

• Row count and file size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
