Sets a new Nodata value on selected bands of a raster feature.

Jump to Configuration

Typical Uses

  • Defining a Nodata value for a raster that does not currently have one set, excluding cells with that value from display or processing.
  • Changing the Nodata value on a raster.

How does it work?

The RasterBandNodataSetter receives raster features, and adds or changes the Nodata property on any selected bands. If a band already has a Nodata value, cells with that value may optionally be changed to the new provided value.

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

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

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

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

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.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
