Google Maps has got fresh competition. Using machine learning, computer engineers have developed an interactive map that shows 3D models of the world's buildings – practically every single one of them. Here's how it works and how you can tinker around with it yourself. 

Called the GlobalBuildingAtlas, the freely available map features nearly all of the world’s 2.75 billion buildings, which presumably includes your home, your favourite restaurant, the hospital you were born in, and so on. Each structure is displayed with a resolution of 3 x 3 meters (approx. 10 x 10 feet), capturing the shape and size of each building with surprisingly good accuracy. 

Around 97 percent (2.68 billion) of the buildings are displayed in the highest level of detail, plus the map contains buildings from regions often missing in global maps, such as Africa, South America, and rural areas.
