                  ~~~  PySAR  ~~~
      Python-based toolbox for post-processing 
      synthetic aperture radar (SAR) data

PySAR is a general-purpose set of tools for common post-processing
tasks involving the use of SAR data.  Interferometric SAR (InSAR) 
and Polarimetric SAR (PolSAR) tools are included along with tools that
are useful for processing 1D data sets, such as GPS and seismic data.
