The thing about the proliferation of technologies like Google Earth is the open source nature of overhead imagery. This provides a largely infinite portal of source imagery for artists and those working in appropriation. The work of Clement Valla, particularly "Postcards From Google Earth" immediately comes to mind. Valla scours the Google Earth for bridges and causeways. The imaging software can't handle these forms accurately, and the results are a bizarre window into a world that only half exists.
Elsewhere, photographer Mishka Henner stitches satellite imagery together into massive prints. In her series "Feedlots" Henner shows overhead views of the immense waste produced by Texas cattle farms, displayed only in the way that aerial photography can.
