Work with data S3A_SL_2_LST in snap

I work with data S3A_SL_2_LST in snap programe. While I subset this data I have mistake.
May be you want me with this problem ?

Can you take a screenshot of the arguments that you have entered in the Subset window?


I have now tried the same and experienced same issue. Which I have confirmed on multiple computers.


When I zoom in, such that the vertical border of the image is not visible and then attempt to perform
“Right click” ->“Spatial Subset from View”,

I get following error:

at org.esa.snap.core.datamodel.TiePointGrid.createSubset(
at org.esa.snap.core.dataio.ProductSubsetBuilder.addTiePointGridsToProduct(

When I zoom in just so that the both vertical image borders are visible the operation can be completed.

Am I missing something or is this a bug?

That’s strange.

it tried it with the same product and it works for me.

Do you have the latest updates (Help / Check for updates)?

I can also get the parameter window. Can you get a subset after clicking ok?

Ah, now I got it. I thought it happens already when the window opens.
I’ve created an issue for it: SIIITBX-192
I’ll have a look and see if it can be fixed easily. But I can’t promise that a fix will be released soon.

Thank you very much.

I had a look at this. It is not only a problem of SNAP. There is information missing in the LST data which allows positioning the tie-points correctly in relation to the scene image data.
I’m in contact with ESA. Let’s see what the outcome will be.

Just to leave a reply on this.
It has been solved with the newest SNAP update which I downloaded on 18 December 2018 :slight_smile:
