Radius of the Earth - Radii Used in Geodesy
clynchg3c.comRadius of the Earth - Radii Used in Geodesy James R. Clynch February 2006 I. Earth Radii Uses There is only one radius of a sphere. The earth is approximately a sphere and therefore, for some cases, this approximation is adequate. The single radius is used for two main purposes: 1. To find the distance between the surface and the center of ...
