Google today revealed Earth VR, a virtual-reality version of the company's famous Google Earth program that's built for the HTC Vive. The application packs the rich Google Earth dataset -- which includes high resolution satellite imagery, elevation data, and detailed 3D modeled cities and landscapes -- into a single model of the planet which users can view all the way from space down to the ground, walking among cities like a giant. The company tells Road to VR that "Earth VR is a product, not a demo," and that it's designed to benefit from improvements in the Earth dataset over time automatically, and it will see regular updates post launch.
