What is Earth's Polar Radius?
Earth's Polar Radius is the radius of the Earth measured from its center to the North or South Pole. Its value is approximately 6,356.8 kilometers (3,950.7 miles), slightly smaller than the equatorial radius due to Earth's oblate shape.
What is a US Survey Chain?
The US survey chain (∼20.1168 m) used the US survey foot. This measurement was key in the rectangular survey system that mapped the American frontier.
