FME Transformers: 2024.1

Related Transformers


Georeferences a raster by either known corner coordinates or origin, cell size, and rotation.

Jump to Configuration

Typical Uses

  • Adding known position information to rasters.
  • Georeferencing rasters with non-spatial content for cartographic purposes.

How does it work?

The RasterGeoreferencer receives raster features and tags them with georeferencing information as provided in the various parameters.

There are two methods of georeferencing available:

Point and Angle

Georeferences based on the known origin (upper left corner) coordinates, cell spacing (cell size), and rotation.


Georeferences based on the coordinates of all four corners of the raster, which must form a rectangle.

A CoordinateSystemSetter may be used in conjunction with a RasterGeoreferencer to provide complete position information.

If the raster is already georeferenced, the existing georeferencing information will be overwritten.

This transformer is unaffected by raster band and palette selection.


Usage Notes

  • Georeferencing does not alter cell values or require interpolation - it only tags the raster with positional information to be interpreted by a product. It differs from reprojection, where the raster itself is transformed from one known coordinate system to another, interpolating new cell values. A Reprojector may be used for this.

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.
