Dead Pixel in Google Earth, hacking satellite maps one pixel at a time
hacking the virtual and real representations of Google Earth (as many artists have done before him), Dutch artist Helmut Smits follows in this continuum with "Dead Pixel in Google Earth". The project is a physical landscaping alteration that burns an 82 cm x 82 cm size square in a field of grass, which measures the equivalent of one pixel of data at an altitude of 1 km when seen with Google Earth.
