FME Transformers: 2024.1

Related Transformers


Removes the existing Nodata identifier from selected bands of a raster feature. Any values previously equal to the Nodata value are considered valid data.

Jump to Configuration

Typical Uses

  • Making cells containing the Nodata value valid for calculations.
  • Making Nodata cells visible in a visualization tool that otherwise renders them transparently.

How does it work?

The RasterBandNodataRemover receives raster features, and removes the Nodata property from any selected bands. It does not alter cell values.

Cells that have the current Nodata value retain their values, and those values become valid for operations such as expression evaluation and statistical analysis.

Nodata represents an absence of data, and cells that have the Nodata value are ignored for most calculations, and are transparent when viewed in the FME Data Inspector and many other visualization tools.

If the raster does not have a Nodata property defined, it will be unaffected by this transformer.

To select specific bands, use the RasterSelector prior to the RasterBandNodataRemover.

This transformer supports raster band selection. Palettes are unaffected.


Usage Notes

Choosing a Raster Transformer

FME has an extensive selection of transformers for working with raster data. They can be generally categorized as working with whole rasters, bands, cells or palettes, and those designed for workflow control or combining raster with vector data.

For information on raster geometry and properties, see Rasters (IFMERaster).

Editing Transformer Parameters

Transformer parameters can be set by directly entering values, using expressions, or referencing other elements in the workspace such as attribute values or user parameters. Various editors and context menus are available to assist. To see what is available, click beside the applicable parameter.
