Use case

When using a map within a GIS, it may be helpful for a user to know their own location within a map, whether that's to aid the user's navigation or to provide an easy means of identifying/collecting geospatial information at their location.

How to use the sample

Select an autopan mode, then use the buttons to start and stop location display.

How it works

Create a MapView.
Get the LocationDisplay object by calling getLocationDisplay() on the map view.
Use start() and stop() on the LocationDisplay object as necessary.
