Reprojects feature coordinates from one coordinate system to another using the REFRAME library. This transformer handles the usual planimetric and altimetric reference frame change 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)

Operating System

• Windows 32

• Windows 64


Raster Parameters

Usage Notes

To perform a reference frame change, select the planimetric and altimetric input and output frames.

The input and output reference frames can be the same (or empty): it allows you to perform only a planimetric or only an altimetric transformation.

For more information about REFRAME, please refer to the documentation available (PDF) or to swisstopo website:

If you are experiencing problems, please check that the following components are installed on your computer:

  • Microsoft Visual C++ 2010 Redistributable Package (x86 or x64)
  • Microsoft .NET Framework 4

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.
