Sparse phase unwrapping for InSAR interferograms
Project description
spurs
Install
pip install spurs
conda install spurs
How to use
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
