GPS Art
GPS Drawing, also known as GPS Art and Strava Art, is a method of drawing where an artist uses a Global Positioning System (GPS) device and follows a pre planned route to create a large-scale picture or text on a map. Artists usually run or cycle the route though cars, vans, and aeroplanes are used to create larger pieces.
