Facebook is using tools like AI and high-res satellite images to create a map of the world population density. This will help ascertain the population density in any given area.
The new systems used by the social media company are quicker and share accurate information about unoccupied land. This is a tedious task if only conventional methods, like satellite imagery, are used.
The company plans to use this data for humanitarian projects like disaster relief and vaccination, though knowing Facebook, there may be commercial aspects as well. It plans to release the maps free of charge for anyone to use.
