Google Maps creation put under the microscope, reveals a human touch
They say you should never learn how the sausage gets made, but we're willing to make an exception for Google Maps. Talking to The Atlantic, Google has revealed just how much the human element figures into all that collected satellite imagery and road data. Many pieces of terrain information are tested and modified against what Google calls Ground Truth: actual driving, alternate sources and sign photos automatically extracted from Street View runs. Google isn't just making the occasional correction, either. Mapping a country can take hundreds of staff plugging away at the company's Atlas tool, even before we get a crack with Google Map Maker. The combination of man and machine helps explain why Google Maps is one of the most accurate sources of location information on Earth -- although the firm does have some catching up to do in space.
Volkswagen 2011 Phaeton can read street signs using windshield mounted camera
Volkswagen's showing off its 2011 Phaeton all over the place, and it's boasting some pretty interesting features if you're the nerdy type. In addition to regular navigational systems, the Phaeton will be the first to integrate a new system which can download Google maps satellite images and points of interest info over a mobile phone, and then laid over existing maps within the GPS, providing a far superior, up to date database of information to the driver. And then there's the camera installed behind the windshield, which can read street sign information such as posted speed limits, no passing zones and the like. It also boasts Dynamic Light Assist, which makes use of the camera to scan the surrounding area for other cars that might suffer from the glare of the headlights, and responds by masking a portion of the lamp to cut said glare. Ah, fahrvergnügen.
