Tele Atlas database includes 1.25million map corrections from users

Tele Atlas has released MultiNet 2009.09, which includes 1.25 million validated edits sourced from community input from more than 30 countries.

Users have provided active input that has helped identify changes, including accurately changing the direction of roads from one way to another, turning older street crossings into the roundabouts they are today and providing exact locations of addresses. GPS measurements have also helped to perfect existing road geometry and add new roads and streets.

In addition to the continued use of community input for updating features such as street names, direction of traffic and gradient measurements, Tele Atlas leveraged anonymous GPS measurements in combination with other sources and processes to validate and realign or extend the world’s road network in the 2009.09 release. This process makes the Tele Atlas road network in these areas even more accurate, to the highest industry standard of at least five meters or 16 feet. Highlights include:

  • The validation and realignment of 116,000 kilometers (72,000 miles) of secondary roads in the United States, a complement to the existing freeway network already in the database;
  • The validation and realignment of approximately 25,000 kilometers (15,500 miles) in Germany, covering the country’s entire freeway network; and
  • The addition of more than 1,400 kilometers (870 miles) of new road geometry in Ireland and more than 1,000 kilometers (620 miles) in Turkey.
