CNN on the big business involved in creating detailed maps—called HD maps—for self-driving cars. “If you believe self-driving cars will eventually operate everywhere, then every city and street will need to be mapped out in granular detail.” How granular? During one test, a single-pixel error on one map caused cars to avoid a patch of road as though it was raised 10 inches. [Osher]

Self-driving cars need extremely detailed and comprehensive maps in order to work—far more detailed than what’s usually available. Paradoxically, Vox’s Timothy B. Lee reports, that’s going to require significant human labour, in the form of human analysts annotating the map. “As Google and its competitors expand their self-driving vehicle programs nationwide, they’re going to have to hire thousands of human analysts to produce the detailed maps that enable cars to drive safely.” [MAPS-L]
