Facebook Is Making a Map of Everyone in the World

Facebook says it has mapped almost 2 billion people better than any previous project. The company’s Connectivity Labs announced that it created new, high-resolution population-distribution maps of 20 countries, most of which are developing. It won’t release most of the maps until later in 2016, but if they’re accurate, they will be the best-quality population maps ever made for most of those places. The maps will be notable for another reason, too: If they’re accurate, they’ll signal the arrival of a new, AI-aided age of cartography.
