"The 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 … See more Let $${\displaystyle \lambda _{1},\phi _{1}}$$ and $${\displaystyle \lambda _{2},\phi _{2}}$$ be the geographical longitude and latitude of two points 1 and 2, and $${\displaystyle \Delta \lambda ,\Delta \phi }$$ be … See more • Air navigation • Angular distance • Circumnavigation See more The shape of the Earth closely resembles a flattened sphere (a spheroid) with equatorial radius $${\displaystyle a}$$ of 6378.137 km; distance $${\displaystyle b}$$ from … See more • GreatCircle at MathWorld See more " - Great circle algorithm
