Singapore’s tree-lined streets may provide much-needed shade and respite from its unrelenting heat, but the same green cover is making it tougher for mapping companies like NavInfo to create the sort of precise maps that cars can use to drive themselves in future.
The tree cover obscures satellite imaging, while wayward tree branches and leaves may block road signs and make it harder for the roof-mounted cameras from capturing the surroundings needed to create a 3D hi-definition map, according to NavInfo.
