Giant Chinese Desert Mystery Structure Solved

Velcroman1 writes "Slashdotters read Monday about strange symbols in the Gobi Desert recently imaged and indexed by Google Maps. Alien landing zones? Some military thingy? Bizarre art project? Nope. The grids of zigzagging white lines seen in two of the images — the strangest of the various desert structures — are spy satellite calibration targets, according to one NASA scientist."

In theory you could mess up the image enough to camouflage your planes from satellite based radar.

Once that's done then they can just tell the damn thing where to go to look at whatever the hell they want to look at.
