StaMPS-HPC Quick Start Dataset: Sentinel-1 InSAR Stack over Beijing (2018)

This dataset is the official Quick Start/Tutorial dataset for the StaMPS-HPC InSAR time-series processing framework. It contains a pre-processed Sentinel-1 Single Look Complex (SLC) stack covering the subsidence zone in Beijing, China. The data spans from January 2018 to June 2018 (12 scenes, Relative Orbit 142, Ascending). To minimize the dataset size while preserving a complete scientific workflow, the spatial coverage has been precisely optimized to 2 Sentinel-1 bursts. The heavy upstream coregistration and formatting have been completed, allowing users to immediately begin testing the StaMPS-HPC pipeline. [ Generation Method ] The stack was generated using the ISCE2 stack processor via the autoInSAR wrapper with the following command: autoInSAR.py --mode stack --lon 116.55 --lat 39.90 --dlonlat 0.15 --start_date 20180101 --end_date 20180601 --rel_orbit 142 --step all [ Contents ] process/: Contains the merged/ subdirectory, which includes the coregistered SLCs, geometry reference files, and spatial baselines. Previews_PNG/: Contains multi-looked amplitude and wrapped phase visualization images generated from the interferograms, allowing users to quickly verify the reliability of the interferometric processing. results/ : Contains spatiotemporal baseline plots, patch division validation files (.kml and .txt), the final exported 3D velocity map (Velocity_Results.kmz), and a stamps_hpc_commands.txt file containing the suggested step-by-step execution commands. GACOS_data/ : Pre-requested GACOS (Generic Atmospheric Correction Online Service) Zenith Total Delay (ZTD) maps, provided to demonstrate the external tropospheric correction module (ps_gacos2tca).
