WebThe great-circle distance, orthodromic distance, or spherical distance is the distance along a great circle.. It is the shortest distance between two points on the surface of a sphere, measured along the surface of the sphere (as opposed to a straight line through the sphere's interior).The distance between two points in Euclidean space is the length of a … The Earth can be modeled as a sphere in many ways. This section describes the common ways. The various radii derived here use the notation and dimensions noted above for the Earth as derived from the WGS-84 ellipsoid; namely, Equatorial radius: a = (6378.1370 km) Polar radius: b = (6356.7523 km)
