One of the ways that Power Map is being used is for kiosks or large public displays– you can create a tour of your BING map, layer on some data from Power Pivot and then have Power Map replay your tour on a loop.
In the latest Power Map update, you can also set up your tour to be on “Auto Refresh” and this will update the underlying data in the Power Pivot model every 10 minutes, ensuring that your display is showing the latest data and to display geo-located data points on a map in near real time.
