In this edit, you point out correctly that the distance from the center to the surface of the earth is less at the poles than at the equator. But what it said was "arcradius". I'm guessing that that means the radius of curvature, which is NOT the distance from the surface to the center, and is larger at the poles than at the equator, because the curvature is less. (I'm not entirely sure that's what was meant, though.) Michael Hardy 00:14, 6 November 2007 (UTC)
