Stack or Collocation

I am searching for the “flags_S.designated_fill_S” expression somewhere in the band properties which causes the error.

Maybe under collocationFlags?

Let me check sir.
I didn’t find the expression “flags_S.designated_fill_S” under collocation flags either.

has this error occurred already before you created the dB bands?

Yes Sir. I can’t open any of the bands after collocation. The same error occurs for all bands.

I tried to reproduce the error with the following steps

  1. Subset and resample L8
  2. Subset and multi-look S1
  3. Terrain Correction of S1 (same UTM zone as L8 product)
  4. Collocation with S1 as primary product

I get the same error:

It is caused by a mask band which was part of the L8 product before Collocation but now has no longer a function…

I delete all masks in the Mask Manager and then save the changes (File > Save product).

Afterwards you can open all bands as usual.

@ABraun Thank u very much, sir. :blush:

That’s actually a pretty old issue, but it should be fixed with the next release.

@ABraun Can you provide the two products you have used for the collocation?
Then I can try with the current development build and check if it is really fixed.
I’ll send you a location wher yuo can upload the data.

Test showed that it is actually not solved, unfortunately.
When we marked the issue as solved we couldn’t reproduce the problem anymore for one scenario.
But for this case I was able to reproduce it. So I hope we can fix it now for the next release.
