file [file ...]

Prepare attributes file for Gamma product.

For each interferogram, including unwrapped/wrapped interferograms and coherence, 3 metadata files are required: 1) reference .par file, e.g. 130118_4rlks.amp.par 2) secondary .par file, e.g. 130129_4rlks.amp.par 3) interferogram .off file, e.g. 130118-130129_4rlks.off

Other metadata files are recommended and can be generated from the above 3 if not existed, more specifically: 4) baseline files, e.g. 130118-130129_4rlks.baseline and 130118-130129_4rlks.base_perp

It can be generated from file 1-3 with Gamma command base_orbit and base_perp)

5) corner files, e.g. 130118_4rlks.amp.corner_full and 130118_4rlks.amp.corner

It can be generated from file 1 with Gamma command SLC_corners)

This script will read all these files (generate 4 and 5 if not existed), merge them into one, convert their name from Gamma style to ROI_PAC style, and write to an metadata file, same name as input binary data file with suffix .rsc, e.g. diff_filt_HDR_130118-130129_4rlks.unw.rsc

For DEM file in radar/geo coordinates (.hgt_sim or .rdc.dem / .utm.dem) and

lookup table file for geocoding (.UTM_TO_RDC), 2 metadata files are required:

1) .par

file, for DEM in geo coordinates and lookup table, e.g.: sim_150911_4rlks.utm.dem.par

2) .diff_par file, for DEM in radar coordinates, e.g. sim_150911_4rlks.diff_par

Here is an example of how your Gamma files should look like: Before loading:

For each interferogram, 5 files are needed:

130118-130129_4rlks.off 130118_4rlks.amp.par 130129_4rlks.amp.par filt_130118-130129_4rlks.cor diff_130118-130129_4rlks.unw

For each dataset, only one sim* folder with 5 files are needed,

sim_150911_4rlks.UTM_TO_RDC sim_150911_4rlks.diff_par sim_150911_4rlks.hgt_sim or sim_150911.rdc.dem sim_150911_4rlks.utm.dem sim_150911_4rlks.utm.dem.par

After running prep_gamma.py:

For each interferogram:

130118-130129_4rlks.base_perp 130118-130129_4rlks.baseline 130118-130129_4rlks.off 130118_4rlks.ramp.corner 130118_4rlks.ramp.corner_full 130118_4rlks.ramp.par 130129_4rlks.ramp.par filt_130118-130129_4rlks.cor filt_130118-130129_4rlks.cor.rsc diff_130118-130129_4rlks.unw diff_130118-130129_4rlks.unw.rsc

For the geometry files in each dataset:

sim_150911_4rlks.UTM_TO_RDC sim_150911_4rlks.UTM_TO_RDC.rsc sim_150911_4rlks.diff_par sim_150911_4rlks.rdc.dem or sim_150911_4rlks.hgt_sim sim_150911_4rlks.rdc.dem.rsc or sim_150911_4rlks.hgt_sim.rsc sim_150911_4rlks.utm.dem sim_150911_4rlks.utm.dem.par sim_150911_4rlks.utm.dem.rsc

Notes: both - and _ are supported;

both YYMMDD and YYYYMMDD naming are also supported; if no multilooking applied, do not add "_4rlks" in your file names.
