Respected I am using the "PyGMTSAR SBAS and PSI Analyses: Lake Sarez Landslides, Tajikistan". However, I got an error while running "Reframe Scenes (Optional)" step. If I skip this step then I get the same error in "Align Images" step.

I’ve rerun the notebook, and it executed successfully:

I am using the scenes and bursts of my own area with coordinates": [73.08, 33.70] for that I am getting this error.

what might be the possible solution for this?

[AlexeyPechnikov]

You need to check that your scenes (bursts) are consistent and cover the area for all dates. The DEM should also completely cover the area.

[abdullahkhanjaan]

what is meant by "cover the area for all dates". Can you explain a bit more please, I am new to using sentinel data.

[AlexeyPechnikov]

If your area is covered by three bursts, you need to define these bursts for all the dates when Sentinel-1 scenes are captured. If you have only one burst for the first date and different bursts for subsequent dates, the processing will not be possible. All the information can be easily checked on the provided plots and in the tables.

you mean to check if the scenes are available after every 12 days or not?

Defined bursts correctly but still got the same result.

Check your DEM and run the reframing command in debug mode for more detailed output:

sbas.compute_reframe(AOI, debug=True)
