Hello, thank you for your good program,
I have a question about comparing GNSS and LiCSBAS data.
I have processed data from GNSS stations, and I have also processed LiCSBAS data for the region where the GNSS station is located.
I convert GNSS data to ground displacement based on LOS.
Can we now compare these two types of data?

Of course, yes. LiCSBAS_cum2tstxt.py will be helpful.

Thank you very much for your help.

I have another question.

GNSS data provide the position of a point in real-time.

My main question is whether the displacements provided by LiCSBAS are relative to the master image?
(In other words, are all interferograms based on the master image?)

Since I also need to align the GNSS data based on the date of this master image and show the displacement changes.

The output of LiCSBAS_cum2tstxt.py is based on the temporal reference of 1st date, but you can set the temporal reference to any date by subtracting the displacement at the reference you want because all values are relative.
