HERE introduces HD Live Map to show the path to highly automated driving
HD Live Map is composed of tiles and contains dynamic content layers. Each layer provides different details: lane level information, dynamic road network and situation changes, and speed profile data. These layers combine long-standing content (HD Map), temporary information (Live Roads), and analytics data (Humanized Driving).
HD Live Map provides much-needed context to data sensed by a vehicle’s on-board sensors, in essence becoming a baseline for all vehicle functions.
In other words, HD Live Map is the “natural canvas” on which to store all the data coming from a car’s sensors and from the cloud so that a car can read them.
While autonomous cars are indeed well-equipped with sensing data, they are recognizing the road for the first time. The HD Live Map can provide context. Sensors have no “memory” for roads: Is a lane divider knocked down? Has a tree fallen into the street?
