Flash Earth

There are a few different mapping services around now, and often you just need whichever one has the best maps for a specific area. Flash Earth gives you a quick and easy way to compare them – just click to select a different service, and it switches to using their maps. Once you’ve found the one with the most detail, you might want to go to that site for the extra features, but at the very least it saves you a lot of time trying several sites out each time.
