Footprint explores ways of mapping information and aerial and satellite photography of the landscape. Together with writer and filmmaker Peter Delpeut, artist Gerco de Ruijter set out on a visual investigation into a phenomenon they encountered on Google Earth while looking at airports. In the winter, planes are stripped of ice. The stencil of an aeroplane remains on the concrete, just long enough for the satellite to photograph it. De Ruijter and Delpeut wondered whether these giant drawings of aeroplanes really belong on a map, or whether Google Earth is not a map, but a unique image of the world. Designer Hans Gremmen created a folding map that provides a range of combinations between image and text. The focus is on Will Rogers World Airport (OKC) in Oklahoma City.
