Topology View – Custom Sprites
The GUI Topology View has the ability to have custom sprites displayed as a layer between the (geographical) background map and the topology elements (nodes/links).
In the current release (1.3.0 "Cardinal") sprite layers are defined in an external JSON format and uploaded to the controller via a REST command. They are loaded into the Topology view by manually adjusting the browser URL to include a "sprites" query parameter. We hope to provide a more user-friendly mechanism (directly through the GUI) in some future release.

File Format
