BBOX is not actually being used

[Carolinah23]

I am creating my stack and I pass a parameter for bbox, but when ISCE is running it creates the stack for all the common area. This is kinda problematic for me becuse it is taking way too much time to run for areas that I don't need and when creating the time series, Mintpy focus in the areas outside the area I am interested in. Is there a way to force ISCE to ignore the areas outside the box?

This is the code that I am using:

#Folders

data_dir="/media/poboy/LaCie/03Shreveport/Data"
process_dir="/media/poboy/LaCie/03Shreveport/stackNorth136_south"
aux_dir="/media/poboy/LaCie/orbits/Sentinel/AUX"
orbits_dir="/media/poboy/LaCie/orbits/Sentinel/Orbits"

os.chdir(data_dir)
print("----------------")
print("Current folder " + os.getcwd())
print("----------------")

ISCE2’s topsStack performs interferometric processing on all bursts covering the specified bounding box (bbox), and note that the processing is burst-wise. Therefore, even if your bbox area is very small, topsStack will still process at least one burst. You can get more details on the algorithm used in topsStack in the following paper:
FATTAHI H, AGRAM P, SIMONS M, 2017. A Network-Based Enhanced Spectral Diversity Approach for TOPS Time-Series Analysis[J/OL]. IEEE Transactions on Geoscience and Remote Sensing, 55(2): 777-786. DOI:10.1109/TGRS.2016.2614925.

Thanks for the clarification! I am processing an area quite big. It is on the middle of two swaths and three to four burst. I guess in this case the stack is going to be created by the four burst in both swaths, not only the area I am interested in, right?
