Persistent Scatterer Interferometry (PSI) Workflow

The Persistent Scatterer Interferometry (PSI) workflow in CATALYST Professional enables users to measure mm ground deformation movements using Synthetic Aperture Radar (SAR) data. The PSI technique leverages a stack of SAR images to identify stable points which ensures reliable measurements.

The complete PSI workflow in Catalyst Professional is divided into seven python scripts. The documentation and scripts are available from the links below.
