Pixel discrepancy sentinel 1 preprocessed series

#1

Good day,

I have a sentinel 1 time series preprocessed (same coordinate system) in which the pixels don´t exactly match from one image to the other. There is a discrepancy of half pixel as you can see below:

How can I solve this issue? Can I apply collocation, coregister or geo-coding tools? The last one is just for SLC products I guess. Or is it something else?

Thanks

Good day,

Or is there a easy way of solving this using python?

Thanks.

It is not really possible to comment on the discrepancy unless you post your pre-processing graph.

Hi,

Here it is :

It was converted to Geotiff, but already tried in snap without converting and it still has a discrepancy.

Thanks.

I think the solution is to stack the two images with CreateStack before doing Terrain-Correction.

I´ll try it and see how it goes.

Thanks.
