I need a SAR-interferometry specialist to run a full Small Baseline Subset (SBAS) workflow on Sentinel-1 IW scenes that cover a post-mining landscape. The goal is to quantify ground deformations/subsidence, tracking it continuously from September 2017 through September 2025.
What I expect PREFERRED SOFTWARE (ENVI SARSCAPE) Preprocess Sentinel-1 SAR data (orbital correction, debursting, co-registration). Generate differential interferograms and perform phase unwrapping. Apply SBAS processing to produce: displacement time series; deformation velocity maps; coherence maps; Remove residual topography, orbital errors, and atmospheric phase; Document workflow, methodology, and tools used.
Deliverables LOS displacement maps Mean deformation velocity maps (mm/year) Deformation time-series for selected points/areas Coherence rasters Written description of workflow and processing steps (If scripts are used) reproducible processing scripts
The outputs must be geocoded in WGS-84 / relevant UTM zone and ready to drop into QGIS/ArcGIS. I will provide the AOI polygon; you handle scene selection and download.
