I thought that was cool too, but then I noticed that the pictures are all computer renderings. They look a bit odd, and the perspective doesn't fit. The background 'corn field' is the same on many of the pictures, and the ground paths look completely featureless and fake. I wonder where the real mazes are? The opening dates are in the future so perhaps the haven't been made yet?
One of my FB friends lives nearby to one of them. http://www.belvedereplantation.com/maze.php
I guess once they get used a bit, or start getting old, or they've had some windy weather, or the aliens come down and churn them up, they tend to go shaggy, so they had to tidy up the images so you get the full impression.
