Feature Layer With a Named Label Source Reference

A feature layer can optionally reference a named label source using the namedLabelSourceRef attribute. This information indicates a label source that this feature layer can be labeled with. You can then either find a label layer containing that named label source to render the feature layer and label layer together, or manually construct an inline label layer inside a Render Map request. The Map Uploader utility inserts the label source reference inside the feature layer when uploading. The reference is only exposed through a Describe Named Layer or Describe Named Layers request in the REST Mapping Service.

Note: The sample named label source in this example will be provided in the /Samples folder as part of the version 12.0 release of Spectrumâ„¢ Technology Platform. For the 11.1 version, use WebDAV to copy the samples from the 11.1 patch zip or tar file to your repository.


This is an example of a feature layer with the namedLabelSourceRef attribute.
