Coordinate System Parameter Location Change

Introduction

With the release of FME 2025.2, you will notice the Coordinate System selection field has moved from several dialogs including Add Reader and Add Writer Dialog.

Coordinate System selection is only relevant to formats that are coordinate system aware, so this field is now displayed alongside other reader/writer parameters when it is relevant. This change improves interface clarity and consistency by centralizing all format parameters to a single configuration dialog.

This article outlines what’s changed, what remains the same, and where to find the Coordinate System parameter. 

What’s Changed?

As of FME 2025.2, the Coordinate System parameter is now configured within the Parameters dialog of each format.

Where You’ll See the Change

Add Reader / Add Writer dialogs:

• The top-level Coordinate System field is no longer displayed.
• To configure it in 2025.2+: Click Parameters > Navigate to the Spatial Group > Coordinate System

Old Dialog vs New Dialog

Transformers with format selection: 

• FeatureReader, FeatureWriter, SchemaMapper:
  • The Coordinate System is now available inside the Parameters dialog.
• DatabaseDeleter, DatabaseJoiner, DatabaseQuerier, DatabaseUpdater, SQLCreator, SQLExecutor:
  • These transformers no longer include a Coordinate System setting. If you need to apply one, please use a CoordinateSystemSetter transformer after reading the data.

• 

• 

Existing Workspaces

Existing workspaces created before FME 2025.2 will continue to function as expected. The Coordinate System parameter will still be visible in the Navigator and can be modified. 

However, if you add or update readers/writers, or insert transformers into an existing workspace, you will see the new interface behavior described above.
