Baidu Eyes HD Maps Business

China’s Baidu is looking into the opportunity of making the detailed high-definition maps needed for autonomous cars to move around safely. In the long-term, Baidu believes that HD maps in China will be a “much bigger business” than the search engine business is today. HD maps are a key piece of the self-driving puzzle – they help autonomous cars know all the important information about the world in which they are operating. They are created by people who drive cars through the streets while gathering data about things such as traffic lights and car lanes.
