haversine formula

Mathematics

noun

A formula involving haversines which allows the shortest distance between two points on the surface of a sphere to be calculated using the longitude and latitude of each point.

For two points on a sphere of radius r and having latitudes λ₁, λ₂ and longitudes ϕ₁, ϕ₂, the distance d between them is given by d = 2r arcsin (√h), where h = haversin (ϕ₂ − ϕ₁) + cos ϕ₁ cos ϕ₂ haversin (λ₂ − λ₁)..

Origin

Early 20th century; earliest use found in Mathematical Gazette.
