Getting a solid GPS location in a city can be tough thanks to all the tall buildings. Skyscrapers reflect the GPS signal and can make your location data go crazy, but now, Google says it can correct for this and give users a much more accurate location. Google is working on an update that will leverage Google Maps’ 3D building data to calculate how buildings interfere with GPS, and it says Android’s new “3D mapping aided corrections module” can correct for GPS bounces.
Google has cooked up a scheme to make GPS work better in cities by correcting for the GPS bounces in the distance calculation. Google’s very “Google” solution for this is leveraging the massive amounts of 3D building data it has available in Google Maps.
