Weird Aerial Photographs in google earth

[watcher2001]

I was looking about the planet today and wandered accross the panhandle of Oklahoma and the SW area of Kansas. All in the US of course, and noticed something strange. In most cases you can look at an aerial view of farmland and it appears as a patchwork of squares and rectangles. However in this area of the country it appears as circles? At first I thought maybe it was bad photos but it looks to cover too wide an area and takes up many different frames. For those with google earth or even using http://maps.google.com type in the coordinates of
37 08'10.60" N 101 21'54.63" W and give it a look.

Can anyone that lives in that area give us some insight?

Google is your friend. It's apparently a central pivot irrgation system commonly used in arid conditions that gives the farms their distinctive shape from the sky.
