Self-processed Sentinel-1 InSAR over the Surat Basin coal-seam-gas fields (Chinchilla–Condamine, QLD) — raw imagery through our own HyP3 + MintPy pipeline. Points coloured by velocity — click to inspect a time-series.
We processed this ourselves end-to-end: raw Sentinel-1 bursts → interferograms (ASF HyP3) → SBAS time-series (MintPy) → trend classification, over the full 2015–2024 record. Velocity is masked for coherence and unwrapping quality, linearly de-ramped, spatially averaged (~400 m) to suppress noise, and re-referenced so stable ground reads zero.

Colours follow OGIA's subsidence convention (green = stable, red = subsiding); apparent uplift sits within our noise floor (residual atmospheric delay, no tropospheric correction applied yet) so it reads as stable. Subsidence tracks the coal-seam-gas well fields, matching OGIA's independent InSAR trends.
