SAOCOM - Dem assisted XCORR

nkalis · March 15, 2024, 8:46am

I am trying to coregister two SAOCOM images in SNAP V9.0.8. When doing DEM assisted and XCORR separately, it runs just fine, but when using the DEM assisted XCORR method I am running into an error (whether through the GUI or through the GPT CLI).

My graph is as follows:

DEMAssistedCoregistrationXCorrGraph.xml (4.1 KB)

And the log shows:

Has anyone else ran into this problem and has managed to figure it out?

JIRA ticket SNAP-3650 created to track this issue

Could you remove the BandSelection operator from the graph and run it again to see if you still have the problem?

Hi Jun, thanks for looking into this!

Running without the BandSeletion operator unfortunately gives me the exact same error.

Hi Jun, any luck in figuring this out? I tried again in the new SNAP10 release hoping for some luck, but I still get the same error.
