Band subset to GeoTiff: already exists error


#1

Hey all,

I’m trying to subset a .dim file, created with C2RCC, to specific GeoTiff’s containing just one band from the original .dim file.
See the GPT graph below:

<graph id="2018-04-06 10:36:58">
  <version>1.0</version>
  <node id="Reader">
    <operator>Read</operator>
    <sources/>
    <parameters class="com.bc.ceres.binding.dom.XppDomElement">
      <file>Landsat8\preprocessed\classified\C2RCC\LC08_L1TP_198024_20140205_20170426_01_T1.tar.dim</file>
    </parameters>
  </node>
  <node id="Subset">
    <operator>Subset</operator>
    <sources>
      <sourceProduct refid="Reader"/>
    </sources>
    <parameters class="com.bc.ceres.binding.dom.XppDomElement">
      <bandNames>iop_agelb</bandNames>
      <copyMetadata>true</copyMetadata>
    </parameters>
  </node>
  <node id="Writer">
    <operator>Write</operator>
    <sources>
      <sourceProduct refid="Subset"/>
    </sources>
    <parameters class="com.bc.ceres.binding.dom.XppDomElement">
      <file>Landsat8\IoP\LC08_L1TP_198024_20140205_20170426_01_T1\iop_agelb.tif</file>
      <formatName>GeoTIFF+XML</formatName>
    </parameters>
  </node>
</graph>

However, when I execute this graph, I get the following error message:

Error: The Product ‘Subset_LC08_L1TP_198024_20140205_20170426_01_T1.tar’ already contains a raster data node with the name ‘iop_agelb’.

This is weird, since I do not define the file ‘Subset_LC08_L1TP_198024_20140205_20170426_01_T1.tar’ anywhere.
Anyone sees what i’m doing wrong here?

Anyone out there with an idea? :slight_smile:

I get the same error when I am processing my images. So I would be happy too, if somebody knows a solution for this problem :slight_smile:
