GPS as a Digital Paintbrush
on 04 October 2014
GPS, it turns out, can be more useful than just telling you how to get places. Cuban-American artist Jorge Rodríguez-Gerada used the very precise technology from Topcon Positioning Systems (used by cartographers and the US Army and Navy) to create "earth art": a gigantic landscape portrait on a plot of land in Washington DC's National Mall. 15,000 stakes were set up as a template, and soil and sand were arranged carefully to distinguish the facial features.
