Hmmm, that doesn't seem right. Just like in real life how the Great Wall of China is the only manmade structure visible from space, it's also the only wonder that shows up on the map.
The Wall is in this picture.
Red are parts that be picked out. Yellow is potentially another visible section. Potentially, because from the ISS, it is not easy picking things out.
As it turns out, the Wonder of the World that can mos easily be seen by astronauts on the ISS
are the Great Pyramids.
Both are taken from the ISS. It's prretty easy to ick out the pyramids here.
Of course, nothing beats 2 other things on easy to see from space objects: Very straight roads and long bridges. Especially if the roads are in rough terrain. This is because very straight lines are not naturally occurring most the time. Especially over water. So these are very easy to pick out because they absolute contrast with their environment by not fitting in.
End result is the astronauts on the ISS can easily use their eyes to see such roads and bridges.
It is also why the Pyramids are easy to see from the ISS, but the wall is impossible.
The wall has a lot of curves to go with the terrain and so cant be easily picked out, or simply can be confused for something else. The Pyramids have a base with 4 straight lines, and the shadow on one edge for contrast which practically scream LOOK HERE, The Great Pyramids.
