On the Google Lat Long Blog, Google Maps Software Engineer Larry Powelson announced the addition of new mobile biking directions and navigation to the Google Maps for Android app. Ten countries have received new biking directions including Australia, Austria, Belgium, Denmark, Finland, the Netherlands, Norway, Sweden, Switzerland, and the UK. In addition to the biking directions, Google added turn-by-turn voice-guided navigation to the Google Maps Navigation (beta) app for every country with biking directions.
Biking routes in Google Maps will show up as different shades or styles of green lines. Dark green lines indicate dedicated bike trails or paths or streets with no traffic. Light green lines designate street with bike lanes. Dashed green lines mark other recommended bike routes.
Users in areas covered by the Google Map Maker feature can add new trails and paths to Google’s database and help their fellow bikers. In all, Google now has over 330,000 miles of bike routes mapped. That translates to over 530,000 kilometers or the half a gigameter mark. If you are ready to hit one of those trails on you bike, just strap your Android device to your handlebars and enjoy a map showing your route or get voice directions.
