InSAR Ground-Deformation Risk Screening

Geotechnical / Earth Systems

Processed Sentinel-1 InSAR time series to measure millimetre-scale ground motion, flagging deformation hotspots to support geotechnical risk assessment of assets and sectors.

The story

Scroll through problem, approach, and outcome.

Problem

Ground-stability risk across a large asset portfolio was hard to monitor without costly, sparse field surveys.

Approach

Built a workflow to process Sentinel-1 InSAR time series, derive line-of-sight displacement, and aggregate per-asset deformation rates into PostGIS for screening and reporting.

Outcome

Enabled portfolio-wide, remote screening of ground-deformation risk, prioritising sites for closer geotechnical investigation.
