Hi,

Is it possible th have more details on the way to use the “S-1 TOPS Merge” module?

Trying to merge 2 products derived from “TOPSAR Coreg Interferogram.xml” with swath IW1 and swath IW2. The following message appears: “TOPSAR-Merge: -1”

Any tips ?

Regards.

Patrick, could you please provide the names of the two IW products you are using and we’ll try to reproduce the issue?
Thanks

@lveci

Last nightly build (SNAP-2.0 beta-8) corrects TOPS-Merge bug.

I don’t think so. The problem was in the metadata produced by the
deburst operator. It saved slant range time to first/last valid pixel as
a float instead of double. This fix only made it in on Tuesday but beta8
was built on Monday.

@lveci,

In fact beta-7 was tag last friday !
You’re last commit (84fe675fc361526e4edc51f490ab57f84dcf68f6) in the git repository solve this bug and should be available in the next release (snap-2.0 beta-8).

Cheers,
Patrick
