Dear all,

I would like to assemble two S1 images in InSAR process because my study area is located between two images but I don’t know in which step of the InSAR process by SNAP I should apply it. Could you please guide me about this issue?

Best regards,
Sayyed

Dear falahfakhri,

Thank you so much. Is it matter to choose all sub-swath before SliceAssembly or I can choose only one sub-swath to do this process?

Best regards,
Sayyed

Use Sub-swath to be assembled,

You can select the ones you need. If you do not select anything all will be processed.

Excuse me, after doing above model to assemble two images, I should do only Back-Geo-Coding for Co-registration process?

Basically after slice assembling, your two images, or two bursts from different neighbours, the two slices became one, So backgeocoding is applied once.

Yes, continue normally, according to your steps.
