Representing the earth as an ellipsoid allows us to approximate distances between points
on the surface much better than a sphere. Ellipsoidal formulas treat the Earth as an
oblate ellipsoid which means accounting for the flattening that happens at the North
and South poles. Lambert's formulae provide accuracy on the order of 10 meteres over
thousands of kilometeres. Other methods can provide millimeter-level accuracy but this
is a simpler method to calculate long range distances without increasing computational
intensity.
