looking for coordinates of the "great wall of china ". it is supposed to be the only a made structure visible fro space but I still a unable to locate it with google earth alone.

It's wider than a couple metres. Major cities have better resolutions as it's more productive for the satellite to focus on these areas than some random fields in the countryside that noone really cares about.
