Despite being continually trumped by Google, Microsoft are intent on having their own search engine, Bing. This search engine also has its own map tool; little surprise there, to be honest. I was however intrigued by one of its features: Bird’s Eye view, looking at the satellite map at an angle reminicent of isometric tycoon games.
Despite limited coverage and rather shoddy image-tile caching, I rather enjoyed the new perspective on things. It might not be as useful as Streetview, but I like to think of it as complimentary rather than a replacement. I recommend checking it out, if only to pretend you are playing the next Sim City.
