>Vincent Creevey, Professional Land Surveyor, Southern New Jersey: "To stake something like this out in the field from a surveying perspective, it's probably going to take a better part of a day and a half to two days work. Because you've got 409 points. You would have to lay out the radius point of every circle in that formation to get it perfectly symmetrical. And the office calculations you would need for something like that would probably take also the better part of a half a day with a computer. And the way this would be laid out would be with an electronic distance meter and a data collector that would already have the coordinates of all the points stored into it. That's how it would be laid out in the field."

OR....

With the very best GPS equipment available, you might be able to lay out each point in about 2 to 3 minutes, and with some of the less expensive equipment, it would probably be about 45 minutes per point."

So, for professional land surveyors to mark 409 circle points and radii at 3 minutes per point would take 20 hours; or up to twelve days at 45 minutes per point before any crop could be laid down.
