 3. Handle location change events to respond to floor changes or read other metadata for locations.
 4. Assign the `IndoorsLocationDataSource` to the map view's location display.
 5. Enable and disable the map view's location display using `StartAsync()` and `StopAsync()`. Device location will appear on the display as a blue dot and update as the user moves throughout the space.
 6. Use the `AutoPanMode` property to change how the map behaves when location updates are received.

 ## About the data
 
-This sample uses an [IPS-enabled web map](https://www.arcgis.com/home/item.html?id=8fa941613b4b4b2b8a34ad4cdc3e4bba) that displays Building L on the Esri Redlands campus. Please note: you would only be able to use the indoor positioning functionalities when you are inside this building. Swap the web map to test with your own IPS setup.
