S-1 TOPS Coregistration error

[chayma]

Hello,

I am trying to follow the S1TBX TOPSAR Interferometry with Sentinel-1 Tutorial in order to process the interferogram of two S1 SLC IW images. However at the step of S-1 TOPS Coregistration I get the following error “GC overhead limit exceeded” (please see the image bellow).
Could you please help me to fix this problem and get the interferogram?

Thank you very much.

This probably indicates that you don’t have enough memory. How much RAM do you have?
Have a look at this post :

SNAP memory issues while importing S3 products

I though 8GB would be enough. I have 16GB and it works for me. Maybe you can increase the amount of memory SNAP can use. Open snap.conf (in etc folder of the installation dir). Ensure that you have write permission. Increase the -J-Xmx value. Maybe to something like -J-Xmx6300M.

It tells you how to tweak the memory setttings.
