Radarcoded DEM dumping

#1

Dear all,
I see in the source code (file SubtRefDemOpUI.java) that the operator “SubtRefDemOp” should be capable to export the elevation band estimated through the procedure “TopoPhase.java”.
How to set up the xml file to provide in input to GPT in order to achieve this goal?
I performed some tests like the following one:

  <node id="TopoPhaseRemoval">
    <operator>TopoPhaseRemoval</operator>
    <sources>
      <sourceProduct refid="TOPSAR-Deburst"/>
    </sources>
    <parameters class="com.bc.ceres.binding.dom.XppDomElement">
      <orbitDegree>3</orbitDegree>
      <demName>SRTM 1Sec HGT</demName>
      <externalDEMFile/>
      <externalDEMNoDataValue>0</externalDEMNoDataValue>
      <tileExtensionPercent>100</tileExtensionPercent>
      <topoPhaseBandName>topo-phase</topoPhaseBandName>
      <outputElevationBand>true</outputElevationBand>
    </parameters>
  </node>

However I got the following error:

Error: [NodeId: TopoPhaseRemoval] Operator 'SubtRefDemOp': Unknown element 'outputElevationBand'

How should I modify the xml file?
Thanks in advance for any suggestion
Best regards

outputElevationBand should work. Could your gpt maybe be going to a different version of snap?

Dear Luis,
really I’m using snap5.0.
The outputElevationBand is not a card available by default in a xml file generated by the graph builder.
I added this card to the “standard” xml but it returns an error.
Then, I ask you what I can do to dump the elevation band specifically generated by the procedure “TopoPhase.java”.
Thanks a lot for any suggestion

I see, you’re looking at the master branch of the source code which does not correspond to the 5.0 release (this would be the 5.x branch). The outputElevationBand is not a parameter in the 5.0 software.

#5

This means that this is not a feature of the actual release (5.0) and that I have to wait for a future release?

#6

That’s correct. I’ll try to get it to you in an update.

Thanks a lot. Best regards
