Facebook has mapped populations in 23 countries

Facebook doesn’t only know what its 2 billion users “Like.” It now knows where millions of humans live, everywhere on Earth, to within 15 feet.
Facebook used satellite-based data and government census information to map the Earth’s entire human population. The data set has a resolution of five meters and knows where man-made structures are everywhere on the planet. Facebook rival Google sold its satellite-imaging business, formerly called Skybox, because they figured out they could get the data without having its own satellites. Of the 576 U.S. satellites now in orbit, 286 — or roughly half — were launched for commercial reasons.
