Error in GPF graph for creating a new band from the multiband Geotiff image

Hi, I moved your to the snap category. The GPF Graph category is intended for presenting working example graphs to others. In an xml file you need to treat some characters special. See here: So your expression must look like: <expression> band_1 &lt; 200<expression> Please note, I’ve also changed the band name. Also you need to remove the <.../> This shall only indicate that you can add multiple of the targetBand definitions.
