Air traffic visualisation. Computer artwork of air traffic over the USA. This image is one frame from an animation of air traffic over a 24-hour period. Air traffic data from the US Federal Aviation Administration (FAA) was plotted using a programming language called Processing and animated using Adobe After Effects and Maya. Plot colour and size were assigned based on aircraft type, location and altitude. This frame shows flight activity over the east coast of USA (right), west coast (left), central USA (centre), Florida and the Caribbean (lower right). The full animation reveals up to 19,000 aircraft flying over the USA at any one time. Created by Aaron Koblin, design and media arts researcher, University of California, USA.
