@bjmarfito
This is huge (length 36864 width 4762)!
The message in your log says that it didn't finish because it is too large
none or more interferogram dimensions too large
The unwrapping in full resolution is a real problem, we usually suggest processing a small region instead of the whole scene. The largest dimension I have processed so far is 12000*6000 and it was not easy
from miaplpy.
@bjmarfito This means that SNAPHU has not finished unwrapping yet, it is merging tiles
If it is takeing longer than 2 hours, check your interferogram (filt_fine.int), it might be too big or totally decorrelated and very difficult (sometimes impossible) to unwrap. you may change your unwrapping network and choose more coherent interferograms.
After SNAPHU is done with unwrapping, the names of the files will be corrected as filt_fine.unw
from miaplpy.
@mirzaees, thank you for providing solutions on the issue I am facing. The unwrapping step was finished but the filename is still the same. For now, I follow your suggestion to change the unwrapping network from sequential to single reference.
I will update you once the processing is finished.
from miaplpy.
@bjmarfito, I still think that your SNAPHU did not finish
do you use jobs? maybe they run out of time
Just a quick note, do not use very long temporal or perpendicular baselines, they are usually decorrelated.
I do not suggest single reference for your case, I would go with delaunay and check the coherence of my interferograms
from miaplpy.
@mirzaees, I used jobs though I set the wall time for 10 days. The unwrapping finished incompletely even though the code prints out that it finished the unwrapping at a time period.
Below is the the log from the unwrapping procedure in MiaplPy.

@mirzaees, I see. Thank you for giving an explanation for the issue I am encountering during unwrapping. Yeah, I would consider your suggestion of using a smaller region for data processing.
from miaplpy.
My unwrapping issue is finally solved by using a smaller region. Thank you for the suggestion @mirzaees!
