Interferogram edges issues

Hi everybody,

I always get edges on my interferograms…

Do you know how it comes ?
And what to do to get rid of them ?

Here an example

Thanks a lot!

Can’t really tell why they occur, but it’s not uncommon. You can get rid of them by creating a subset as shown on page 15 of this tutorial: DEM generation with Sentinel-1 - Workflow and challenges

Thanks a lot for the answer.

The problem is that I need to get rid of it automatically, so subseting is quite a though solution.
Means that I need to generate a fonction to compute where pixels got a non-zero value, and return the 4’th relatives pixels corresponding to first/last of line/column.
Looks ugly but still possible

If there is another way, my ears are open :slight_smile:

Thank you!

you could also simply take the extent of the image before interferogram generation and use this for clipping

Oh great, I did not pay attention that the edges were outside the original frame.
Thanks again!
