Where Do You Go?
Where Do You Go? allows Foursquare users to create a heat map of their travels. Once you log into the site with a Google account and then authenticate with Foursquare you can create a heat map that visualises your location data using color on Google Maps.
Denser concentrations of color on the map indicate more Foursquare check-ins at a venue at that particular location.
SocialGreat is another mashup using the Foursquare API and Google Maps. The site uses data from Foursquare to show what are the current most popular places in cities and uses the Google Maps API to show where those places are.
SocialGreat tells you which bars, restaurants and hot spots in FourSquare cities are "great" according to a near real-time feed of "social" location data from Foursquare users. You can use the map to check which spots are the most popular this hour, day, week, or month.
Peek Maps is a free embeddable widget that shows your recent location on a Google Map and can be placed into a web page, blog, or sent as a link and shared with whoever you want.
If you are a Foursquare user, you can have your recent check-ins appear on your Peek Map.
Ul.timate.info is a FireFox add-on that allows you to check-in to Foursquare from any computer using IP and wifi based location services.
When you run the add-on the first thing that will appear is a Google Map of where you are. You can then update Foursquare with you location as well as your Facebook, Myspace, FriendFeed and Twitter accounts.
