GPS Drawing

GPS Drawing combines art, travelling (walking, flying, and driving) and technology and is a method of drawing that uses GPS to create large-scale artwork. Global Positioning System receivers determine one’s position on the surface of the Earth by trilateration of microwave signals from satellites orbiting at an altitude of 20,200 km. Tracks of a journey can automatically be recorded into the GPS receiver’s memory and can be downloaded onto a computer as a basis for drawing, sculpture or animation. This journey may be on the surface (e.g. walking) or taken in 3D (e.g. while flying).

The idea was first implemented by artists Hugh Pryor and Jeremy Wood, who have drawn a 13-mile wide fish in Oxfordshire and spiders whose legs reach across cities. They have also provided an answer to the question ‘What is the world’s biggest ‘IF’? It happens to be a pair of letters, ‘I,’ which goes from Iffley in Oxford to Southampton and back, and ‘F” which traverses through the Ifield Road in London down to Iford in East Sussex, through Iford and back up through Ifold in West Sussex. The total length is 537 km, and the height of the drawing in typographic units is 319,334,400 points.
