Hello, I am using ISCE2 to process Sentinel-1 data from 2014 to 2025. My area of interest (bbox) lies within the overlap zone of two adjacent satellite swath paths (frames).
Frame 1 (2014-2016): Frame ID 486
Frame 2 (2016-2025): Frame ID 482
I am working with bursts from the IW1 and IW2 subswaths. My resulting velocity map shows blank (NaN) areas. The blank space on the left is expected, as it falls outside the coverage of the IW1 I processed. However, I don't understand the cause of the blank space at the top of the image.
Has anyone encountered this and knows what might be happening with the top blank area? I've attached a graphic showing the two frames, my bbox, and the velocity map.

Hello,
I am trying to process sentinel 1 data from 2022-2025 for my area of interest. My resulting velocity map shows only area around reference point.
Can anyone please guide me on this.
