pip install spurs

conda install spurs

Installation will create a command line script spurs:

spurs 20150608_20170808.int

By default, will output to file 20150608_20170808.unw matching the name.

To increase the tolerance (from pi/10 radians) for faster convergence, showing iteration stats:

spurs 20150608_20170808.int -o 20150608_20170808.unw --tol .5 --debug

See spurs --help for all options.

Note that for input interferograms which aren't complex, float32 binary format, gdal must be installed. E.g. for a VRT input:

spurs 20150608_20170808.vrt -o 20150608_20170808.unw
