everything you posted (except Tokyo) is satellite imagery only as far as i can see - so where is your point?

  Really? In Niue you can see the lines on the basketball court. The best commercial satellite imagery I know if is about .5 meters (20 inches). Now that I look at it though, the Moscow one is pretty fuzzy...

    "Detect" and "resolve" are two different things when it comes to imaging. You can detect the lines on the court because they're bright white on dark background. However, you can't tell if it's one line or two parallel white lines less than ~1m apart. In other words, you can't accurately measure the width of an object less than the resolution of the imagery, even if you can tell that it's present. The Niue imagery is ~1m resolution. If you hunt around a bit, you can find a few cars. Note that you can measure their width, but it's difficult to do.
