HD map strength hinges on freshness and data sources

Digital location technology is revolutionising route planning for drivers, turning static paper maps into dynamic navigation systems. But as vehicles take on a larger share of the driving responsibility, a much more detailed picture of the road is required. Maps must be able to provide a whole new level of information in order for the vehicle to know where it is, what's happening around it and what lies up ahead. That means everything from lane geometry to road furniture and traffic signs, and in a fully autonomous vehicle (AV), the accuracy and precision demands on these maps increase exponentially.
