CoordinateSystemExtractor

Retrieves the FME coordinate system name of the feature into an attribute.

Jump to Configuration

Typical Uses

  • Identifying the coordinate system of a feature or dataset.

How does it work?

The CoordinateSystemExtractor receives any type of geometry and retrieves its FME coordinate system name, adding it to the features as an attribute.

If the input feature does not have a coordinate system defined, or if its coordinate system is not present in the FME coordinate systems file coordsys.db, the attribute value will be blank.

Examples

Usage Notes

Working With Coordinate System Transformers

FME inherently supports coordinate system transformations and reprojections, using the CS-Map coordinate system library.

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.
