The Haversine components is: `a = sin²(Δφ/2) + cos φ1 ⋅ cos φ2 ⋅ sin²(Δλ/2)` `c = 2 ⋅ atan2( √a, √(1−a) )` `d = R ⋅ c` The place:

`φ` is latitude, `λ` is longitude, `R` is earth’s radius (imply radius = 6,371km)

`Δφ` = `φ2`
`φ1`

`Δλ` = `λ2`
`λ1`

`a` is the sq. of half the chord size between the factors.

`c` is the angular distance in radians.

`d` is the gap.
