This is what a mass evacuation from a city looks like from space. Using satellites orbiting over Africa, human rights groups published UNOSAT satellite imagery to show, in very simple terms, the human cost of violence in the Chadian capital city of N'Djamena. Over 10,000 people are crammed on a bridge, trying to escape into the neighboring nation of Cameroon. The black dots are people, and the yellow dashes are vehicles, most likely trucks and buses. It's a chilling portrait of the human future, wracked with violence and recorded via space-based surveillance devices, taken on February 27. See the full map below.
