Problem in Sentinel-1 IW data stack processing

Added by Zhiliang Zhang 11 months ago

Dear all members:
I want to use stackSentinel.py to do sentinel data stack processing, and I will designated study area. But when I do processing, I found that no matter how I set the study area, the number of columns in range direction is always equal to the IW sub-strip total columns!
For example, I set the study area '49 50 120 121', the samples is 25488 and when I set the study area '49.5 50 120 120.5', the sample is also 25488. Could you tell me whether the ISCE can do range cutting? And how can I change the samples according to my research area?
Thank you very much!
Best wishes to you!

For TOPS data, cropping is performed by bursts and not by lines/samples.
For stripmap data, cropping is performed by lines/samples.

You can always perform a subset of the burst after the processing is done for TOPS data.
