Of course, they have inspired their own competition as Microsoft is coming out with their own version of maps, which look quite cool. I'm looking forward to their release, but I imagine that Google's final maps will add some of the same features soon.
As the best currently available, though, it didn't take long for the Google maps to be 'hacked' (channelling address or GPS info through the Google open source interface to create an easy-to-read map). Thanks to Chicagoist and other sites, here are some of the cool things you can view:
- look up locations of the Craigslist Housing Listings
- find Chicago crime stats from February through last month on chicagocrime.org
- a live map showing three companies' taxi locations in Chicago on Ridefinder
- integration of traffic.com into a live Chicago traffic map
- view a CTA map as a part of Google Maps
- a combination of Flickr and Google to show where pictures were taken
- stitch Google satellite pictures from anywhere in the world into desktop wallpaper
- link in your GPS to get a live, moving map of your current location
- find the current lowest gas prices in your area
Finally, some ambitious people have found some pretty neat things amongst the satellite photos. One of my favorites is the aerial view of the White House.
