In 2015, Audi, BMW and Mercedes-Benz united to buy the mapmaker Here, seeing its high-resolution maps as crucial to the development of autonomous cars. Now, another well-established map supplier is trying to meet that emerging demand in the U.S.
TomTom, the No. 2 supplier of maps for in-car navigation systems, said it was ready to deliver similar maps for more than 15,000 miles of highways in California and Michigan, two key testing grounds for autonomous vehicles.
The high-resolution maps, which include the precise locations of lane markers and streetlights, tell a car what to expect as it drives down the road so it doesn't need to rely solely on cameras and sensors.
