NAME

       mintpy-prep_snap - Prepare attributes file for SNAP products.

DESCRIPTION

       usage: prep_snap.py [-h] file [file ...]

       Prepare attributes file for SNAP products.

              For  each  interferogram,  coherence  or  unwrapped  .dim  product this script will
              prepare.rsc metadata files for for mintpy based on .dim metadata file.

              The SNAP .dim file should contain all  the  required  sensor  /  baseline  metadata
              needed.    The   baseline   metadata   gets   written  during  snap  back-geocoding
              (co-registration).  prep_snap is run separately  for  unw/ifg/cor  files  so  needs
              separate  .dim/.data products with only the relevant band in each product. Use Band
              Subset > save BEAM-DIMAP file.

              The  file  name  should  be  yyyymmdd_yyyymmdd_type_tc.dim  where   type   can   be
              filt/unw/coh.

              The  DEM should be prepared by adding an elevation file to a coregestered product -
              then extract the elevation band only. Use Band Subset > save BEAM-DIMAP file

              Currently only works for geocoded (terrain correction step in SNAP) interferograms.

   positional arguments:
       file   SNAP data file(s) in *.img format.
