Three updates to Google Maps were announced at Google I/O today. The big one is an immersive view mode that creates a digital model of a city from aerial imagery and Street View: it’s coming later this year to London, Los Angeles, New York, San Francisco and Tokyo, with more cities coming later. It’s not just about 3D models of buildings—Apple’s got those—but also interiors, as Google CEO Sundar Pichai demonstrated in the keynote.

Also announced: an expansion of eco-friendly routing to Europe and making Live View available to third-party apps. More coverage: Engadget, TechCrunch, The Verge.
