NAME

       mintpy-remove_ramp - Remove phase ramp

DESCRIPTION

       usage: remove_ramp.py [-h] [-m MASK_FILE]

       [-s {linear,linear_range,linear_azimuth,quadratic,quadratic_range,quadratic_azimuth}]
              [-d DSET] [-o OUTFILE] [--save-ramp-coeff] [--update] file

       Remove phase ramp

   positional arguments:
       file   File for ramp removal

   options:
       -h, --help
              show this help message and exit

       -m MASK_FILE, --mask MASK_FILE
              mask for pixels used in ramp estimation default - maskTempCoh.h5 no - use the whole
              area

       -s {linear,linear_range,linear_azimuth,quadratic,quadratic_range,quadratic_azimuth}
              type of surface/ramp to remove, linear by default

       -d DSET, --dset DSET
              dataset name to be derampped in ifgramStack file e.g.: unwrapPhase

              unwrapPhase_bridging

       -o OUTFILE, --outfile OUTFILE
              Output file name.

       --save-ramp-coeff
              Save the estimated ramp coefficients into text file.

       --update
              Enable update mode, and skip inversion if: 1) output file already exists,  readable
              and newer than input file 2) all configuration parameters are the same.

   example:
       remove_ramp.py
              timeseries.h5      -m maskTempCoh.h5

       remove_ramp.py
              ifgramStack.h5     -m maskTempCoh.h5  -d unwrapPhase_bridging

       remove_ramp.py
