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 …

InSAR User Manual

Radar interferometry is a technique which combines the coherent phase from a pair of syntheticaperture radar (SAR) signals to provide three-dimensional information about the Earth’s surface.The technique requires the coregistration and processing of two SAR signals from very similarviewing geometries which have been acquired over the region of interest. By coherentlycombining the signals from the …

InSAR Processing – Deformation and Topographic Workflows

A series of Python scripts has been developed to process InSAR data using Geomatica’s InSAR algorithms. This document outlines both the deformation and topographic workflows and includes additional information on running each of the Python scripts. It is recommended that you follow the document while running the scripts to complete the workflows. InSAR Automated Processing …
