You are here: Rasters > RasterBandNodataSetter


Identifies a value to act as a nodata identifier on a raster feature at the band level. That is, values equal to the specified value will now be considered invalid, and will not be affected by many operations (e.g. offsetting or scaling).

All selected bands on an input raster feature will receive the same specified nodata value.

Usage Notes

  • This transformer supports raster band selection: see the RasterSelector.
  • If different nodata values are desired on each band (for example, when setting nodata values on a color raster, where each of the red, green, and blue bands has a different value), then add multiple RasterBandNodataSetter transformers using either different band selections, or by using raster band splitting to separate the bands on which to set the nodata value.
  • This transformer does not set the nodata value on the palette level. To set the nodata value on the palettes of a raster, use the RasterPaletteNodataSetter.

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
