Error when selecting multiple bands from SLSTR file

Optical Toolbox
#1

Hi,

I am trying to extract and write to geotiff a specific band from SLSTR data as well as the SZA using gpt and a xml graph. I manage to extract the band alone [DEBUG_SLSTR_ex1.xml (976 Bytes)
] and the SZA alone DEBUG_SLSTR_ex3.xml (973 Bytes)
but when trying to combine the two steps in a single graph DEBUG_SLSTR_ex2.xml (1.5 KB) I get the following error:

Error: [NodeId: BandSelect_04] Operator ‘BandSelectOp’: Value for ‘Source Bands’ is invalid: ‘S4_radiance_an’

Can someone see what I am doing wrong?

Thanks!

Probably this issue is the reason: https://senbox.atlassian.net/browse/SIIITBX-245
This might get fixed with the next version.
As a workaround, you can add a read node add the beginning of your graph.

...
<node id="SLSTR_Product">
<operator>Read</operator>
<sources/>
<parameters>
  <file>${slstrFile}</file>
  <formatName>Sen3</formatName> <!-- Sen3 ensures that SLSTR is read as multisize -->
</parameters>
</node>
<node id="bandMathsNode">
<operator>BandMaths</operator>
<sources>
<sourceProducts>SLSTR_Product</sourceProducts>
</sources>
...

Probably you need to add a resampling node too. The bands need to have a common resolution.

Thanks Marco, that was the issue!

Here is the final xml: DEBUG_SLSTR.xml (2.1 KB).

The path of the file should be given as parameter to gpt:

gpt DEBUG_SLSTR.xml -Ssource=SLSTR_scenes//S3A_SL_1_RBT____20180808T104851_20180808T105151_20180809T151857_0179_034_208_1620_LN2_O_NT_003.SEN3/xfdumanifest.xml -Ppathfile=SLSTR_scenes//S3A_SL_1_RBT____20180808T104851_20180808T105151_20180809T151857_0179_034_208_1620_LN2_O_NT_003.SEN3/xfdumanifest.xml -PtargetFolder=SLSTR_out/20180808T104851
