- 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.Methods
Global Positioning System receivers determine one's position on the surface of theEarth bytrilateration ofmicrowave fromsatellite sorbit ing at analtitude of 20,200 km. Tracks of a journey can automatically be recorded into theGPS receiver's memory and can subsequentially bedownload ed onto anelectronic computer as a basis for drawing,sculpture oranimation . This journey may be on the surface (e.g. walking) or taken in 3D (e.g. while flying).Practitioners
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 fromIffley inOxford toSouthampton and back, and "F" which traverses through the Ifield Road inLondon down to Iford inEast Sussex , throughIford and back up through Ifold inWest Sussex . The total length is 537 km, and the height of the drawing intypographic unit s is 319,334,400 points. The text you are reading is about 10 points.External links
