LiCSBAS_decomposeLOS.py about licsbas HOT 18 CLOSED

Sorry for unclear documentation. I should add some explanations into the usage.

As written in the usage, the input files must be in GeoTIFF format, which can be created by LiCSBAS_flt2geotiff.py from float files (e.g., GEOCml1/E.geo).

dispfile1 can be made from TS_GEOCml1clip/results/vel.mskd by LiCSBAS_flt2geotiff.py, or the vel file itself can be created by LiCSBAS_cum2vel.py with a specified span and/or reference area.

Sorry for late replying.
So, first, I need to make vel.maskd.geo.tiff, E.geo.tiff, N.geo.tiff form vel.maskd, E.geo, N.geo,
and then, if I move all files to same folder, should I type as below ?

LiCSBAS_decomposeLOS.py -f vel1.maskd.geo.tiff, E1.geo.tiff, N1.geo.tiff vel2.maskd.geo.tiff, E2.geo.tiff, N2.geo.tiff

from licsbas.

The argument of -f is "Text file containing input GeoTIFF file paths." You must create a text file, e.g.,

cat << EOF > files.txt
vel1.maskd.geo.tiff E1.geo.tiff N1.geo.tiff
vel2.maskd.geo.tiff E2.geo.tiff N2.geo.tiff
EOF

and then run LiCSBAS_decomposeLOS.py -f files.txt.

You don't need to move the files because the text file can contain the path (though you can move the files of course).

Has the problem been solved?

Sorry to late replying.
I missed solving as I have been sick since last week.

Dear Yuorishita,

I have two questions,

1. Which directory do we run LiCSBAS_decomposeLOS.py from? Is any directory okay?
2. How to create 3D deformation of each date (not velocity)?

from licsbas.

1. Any directory is OK as long as you indicate the correct path to the input files for the -f option.
2. LiCSBAS_decomposeLOS.py decomposes into EW and UD, not 3D. The GeoTIFF file of the deformation for each date can be created by LiCSBAS_cum2flt.py and LiCSBAS_flt2geotiff.py. However, we should note that the ascending and descending data have different observation dates.

from licsbas.

Thanks very much Yumorishita. Do you have a python code for generate 3D deformation LiCSBAS?

from licsbas.

I am developing it but currently have no plan to publish it.

from licsbas.

Thanks for your information. I am looking forward to hearing your best codes for 3D deformation.

By the way, can we use unwrapped interferograms generate by using other software such as GMTSAR? If yes, how to prepare files for LICSBAS? As I know, LiCSAR doesn't cover all area and all time but only small percents of them.

from licsbas.

Yes, please see the file structure. The required files are cc, unw, EQA.dem_par and slc.mli.par only.

from licsbas.

Are cc and unw in range-azimuth coordinates?

from licsbas.

Either in range-azimuth or geographic coordinates can be processed, though some functions cannot be used in range-azimuth coordinates

from licsbas.

Thank you very much.

I have slightly updated the usage of LiCSBAS_decomposeLOS.py. Let me close this issue because there seem to be no more questions. If someone has any questions, please reopen this.

from licsbas.

I'll try updated tone. Thanks.
