HIT: Crop aerial views

[Brenda Stafford <staffbha@HOME.COM>]

Thanks to all who helped with the crop circles target.  For those who were
interested in the information gathered on the crop circles, here goes.
The circles are crops watered by pivot or circular irrigation is midwestern
areas.  Using Google "Images" I found some graphics to give the teacher.
Also, it seems that the John Deere monthly magazine Furrows had an article
concerning crop art which is interesting also.  I have not been able to find
a copy of this in coastal Virginia.
"The January 2002 issue of The Furrow has a lengthy
article with lots of pictures. Stan Herd is the artist. He calls it earth
art or crop art. Many of his works are located in Kansas. The address of the
publication is: John Deere, P.O. Box 663, Moline, IL 61266-0663. An
Editorial address is: John Deere Agricultural Marketing Center, 11145
Thompson Avenue, Lenexa, KS 66219-2302."

Also:
Perhaps the web-site of the National Council of Teachers of Mathematics
(NCTM) might provide you with help on this.  Their journals (Arithmetic
Teacher, Mathematics Teacher) might have handled this topic at some point.

The address for NCTM is  http://www.nctm.org

In addition:
The fields are watered with a sprinkler system that pivots around a central
point creating a circle of
green against a brown or lighter green background.  In the fall in Kansas
when the milo maize is ripe the circles will be a rich reddish brown.  The
geometry is very striking.  Square fields will have a single big circle.
Rectangular fields will have one big circle and remaining space filled with
varying numbers of smaller circles.  In cases where local geography or the
existence of houses or bars make a full circle impossible, the circle will
have wedges of varying sizes cut out of it.  There are also concentric
circles where watering systems of different sizes have been used.  I don't
know where to find photographs but maybe trying for aerial views of farms in
Kansas or Nebraska would work.   Also try searching under irrigation
systems.
 I think they are called central pivot systems.

The  crop artist referred to earlier/related but not what my teacher saw:
There's a gentleman named Stan Herd who creates art out of crops.  This may
be what she saw.  Here's a web site that shows a lot of this work.

Another suggestion but pictures are protected:
I went to www.photostogo.com and did several searches.  The best one being
aerial crop views.

Thanks to all,
