CoordinateSystemSetter

Assigns a user-specified coordinate system to features, without modifying geometry or coordinates.

Jump to Configuration

Typical Uses

  • Adding missing coordinate system designations
  • Adding coordinate system designations when the feature's original format does not support them
  • Fixing incorrect coordinate system designations

How does it work?

The CoordinateSystemSetter receives any feature and assigns a user-specified coordinate system to it. No geometry is modified, and data is not reprojected.

The coordinate system may be entered explicitly or set to an attribute value, user parameter, or conditional value.

If a feature already has a coordinate system assigned, it will be overwritten.

Examples

Usage Notes

  • If the coordinate system is not known, this transformer cannot be used to determine it. You will need to assess the units and extents of the coordinates to try to make a manual determination.
  • Similarly, FME won’t carry out checks to ensure that any coordinate system selected is appropriate to the current data.
  • You don’t need to use this to tag features before reprojecting them, as long as the reprojection is done via a transformer. Set the coordinate system in the chosen reprojection transformer’s Source Coordinate System parameter.

Working With Coordinate System Transformers

FME inherently supports coordinate system transformations and reprojections.

Parameters

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.
