Google Maps has been the built-in maps application on iOS since it was first introduced in 2007. But now there's pretty solid evidence that iOS 6, which is expected to be previewed to developers in June, will replace that with Apple's own Maps application. 9To5Mac broke the news and offered a mockup of a new 3-D feature that is generating excitement.
Of course, any map database is a huge project -- the world is a big place. Apple's in-house map database is the result of the purchase of three different mapping companies in recent years. This includes C3 Technologies, which has developed technology similar to Google's Street View. But more importantly, it's also developed an interesting 3-D technology based on, according to 9To5Mac, "beautiful, realisitic graphics based on de-classified missile target algorithms." These algorithms allow quick and efficient construction of 3-D images. This 3-D view will be off by default in the new Maps app and can be enabled by the user. It will be fun to see this new Maps application.
