There are shadows of the tennis court light poles, fence, and net. It is a real tennis court and not painted on the ground.

Then the question is if one is going to the trouble and expense of building a tennis court, why put it on a rolling hill and not level it?

Either way, it's weird!

Maybe Google's elevation data comes from a different (perhaps older) database than the photographic data. Then what you're seeing is the photographic pixels superimposed on the elevation data.
