Skyhook, UDig, and the Country Music Association have collaborated to create a real-time map of geotagged mobile activity around the 2010 CMA Music Festival in Nashville from June 10 - 13.

The map will use Skyhook’s new data intelligence service SpotRank, which identifies the density of people in predefined urban square-block areas worldwide at any hour, any day of the week.

Visit http://skyhookwireless.com/spotrank/CMA.php to see Foursquare checkins, Tweets, Flickr photos, Music Fest concerts, and a heat map of all the mobile location requests coming out of Nashville. You can choose the speed at which the map plays, or just put it on autoloop and sit back and watch.  Move the time slider to show 8:30 pm on Thursday (6/11).  You will see a huge jump in activity at the LP Field concert stage, around the same time that Alan Jackson took the stage.  People were checking into the concert via Foursquare, commenting on the show on Twitter, and tagging photos like this one:

Over the course of festival SpotRank will give observers an exciting new view into the way that mobile device users interact with location-aware apps and how they move around a one-time event.
But looking forward, Music Fest serves as an example for how people are starting to use location-aware mobile apps and devices all over the world.
