Reprojects feature coordinates from one coordinate system to another in Switzerland, using the Reframe library from the Federal Office of Topography (swisstopo).

Jump to Configuration

Typical Uses

  • Reprojecting features when explicitly using the Reframe library is desired

How does it work?

The ReframeReprojector receives raster, vector, or point cloud features and reprojects their coordinates from one coordinate system to another, using the swisstopo GeoSuite Reframe library.

It handles typical planimetric and altimetric reference frame changes for Switzerland. The following Swiss reference frames are supported:


  • Plane coordinates LV03 (CH1903)

  • Plane coordinates LV95 (CH1903+)


  • National levelling network LN02 (levelled heights)

  • National height network LHN95 (orthometric heights, CHGeo2004)

  • Ellipsoidal heights (Bessel)

See Local Swiss reference frames at swisstopo for more information.

To perform a reference frame change, select the Source and Destination Planimetric Reference Frame and/or Source and Destination Altimetric Reference Frame as required.

The Source and Destination reference frames can be the same or blank, allowing for planimetric-only or altimetric-only transformation.

Usage Notes

  • FME has a Workspace Parameter, Reprojection Engine, that may be set to either FME (CS-Map) or Esri. This transformer will override this parameter setting.

  • The Reprojector provides similar functionality, and will use the default library (CS-Map or Esri) set in FME. It supports some Swiss coordinate systems, but will not use the Reframe library.

Working With Coordinate System Transformers

FME inherently supports coordinate system transformations and reprojections.

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.
