NAME¶

mintpy-prep_hyp3 - Prepare attributes file for HyP3 InSAR product.

DESCRIPTION¶

usage: prep_hyp3.py [-h] file [file ...]

Prepare attributes file for HyP3 InSAR product.

For each interferogram, the unwrapped interferogram, coherence, and metadata the file name is required e.g.:

1) S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_unw_phase.tif
2) S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_corr.tif
3) S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2.txt
    

A DEM filename is needed and a incidence angle filename is recommended

e.g.:

1) S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_dem.tif
2) S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_lv_theta.tif
    

This script will read these files, read the geospatial metadata from GDAL, find the corresponding HyP3 metadata file (for interferograms and coherence), and write to a ROI_PAC .rsc metadata file with the same name as the input file with suffix .rsc, e.g. S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_unw_phase.tif.rsc

Here is an example of how your HyP3 files should look:

Before loading:

For each interferogram, 3 files are needed:

S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_unw_phase_clip.tif
S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_corr_clip.tif
S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2.txt
    

For the geometry file 2 file are recommended:

S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_dem_clip.tif

(required)

S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_lv_theta_clip.tif (optional but recommended)

After running prep_hyp3.py:

For each interferogram:

S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_unw_phase_clip.tif

S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_corr_clip.tif

S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2.txt
    

For the input geometry files:

S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_dem_clip.tif

S1AA_20161223T070700_20170116T070658_VVP024_INT80_G_ueF_74C2_lv_theta_clip.tif

Notes:

HyP3 currently only supports generation of Sentinel-1 interferograms, so some Sentinel-1 metadata is hard-coded. If HyP3 adds processing of interferograms from other satellites, changes will be needed.
