PyRate documentation

This is the documentation for the PyRate software.

PyRate is a Python tool for estimating the velocity and cumulative displacement time-series of surface movements for every pixel in a stack of geocoded unwrapped interferograms generated by Interferometric Synthetic Aperture Radar (InSAR) processing. PyRate exploits distributed scatterers using a “Small Baseline Subset” (SBAS) processing strategy and currently supports input data in the GAMMA or ROI_PAC software formats. Additionally, the European Space Agency SNAP software version 8 has a “PyRate export” capability that prepares SNAP output data in the GAMMA format for use with PyRate.


  • Support and development of ROI_PAC has been discontinued.

  • ROI_PAC support in PyRate will be deprecated in a future release.

The PyRate project started in 2012 as a partial Python translation of “Pirate”, a Matlab tool developed by the University of Leeds and the Guangdong University of Technology.
