Today, Microsoft launches a new version of Bing to compete with Google and Apple in the 3D mapping space.
The map featured in video game Grand Theft Auto V is 49 square miles of virtual reality-a massive undertaking for the developers behind the project. The average city in Bing's new 3-D mapping app, on the other hand, covers 154 square miles--and the service is launching with more than 70 of them, amounting to roughly 121 trillion pixels of imagery.
