Google Mapspotting

The mapspotting trend continues to rise as thousands pour over the detail of their Google Earth and Google Maps satellite images.

Uncovering this rooftop airstrip in New York. (Close the push-pin to see the airplane). And this aerial hack where a farmer has written his name on his land.

If this trend continues, it won't be long until the aerial view of the Earth looks like a billboard.

How long, I wonder, until some crafty company leases out land for selling banner ads by the square mile?
