May 08, 2009 · I recommend the Haversine formula in computing because it is accurate enough and performs better than the other two methods. Based on my research (see references) the Spherical Law of Cosines is slightly more accurate than the Haversine formula for most coordinates, but is unreliable for shorter distances because the "inverse cosine is ill ...

In the haversine formula, the manner in which it progresses towards a solution, there are two sqrt() methods in the atan2(). The a that is calculated and then used in the sqrt(), can, at the antipodal points on the globe, slightly stray below 0.0 or above 1.0, very slightly because of fp64 approximations and rounding, rarely, but repeatably.

In this example, we use longitude and latitude info from all US airports to derive the average (mean) distance between every two US airports. The function I will be replacing with C++ is the function to compute the distance between two longitude latitude pairs (Haversine's formula) on a sphere (which is just an approximation).

Also, this formula is unreliable for small distances because the inverse cosine function is ill-conditioned. Here is the Haversine formula : a = sin^2(L2-L1)/2) + cos(L1) * cos(L2) * sin^2((G2-G1)/2) c = 2 * arcsin(min(1, sqrt(a))) // distance in radians distance = 60 * c // nautical miles

The required distance can be calculated from Equation (2) using the inverse Haversine function. The weight ω i,m for the ith point (x i, y i) in month m is then given by the mean d between the ith point and all other extant points in that month. This approach is used rather than Euclidean distances, because it accounts for the curvature of the ...

Historically, the use of this formula was simplified by the availability of tables for the haversine function: hav(θ) = sin 2 (θ/2). Although this formula is accurate for most distances, it too suffers from rounding errors for the special (and somewhat unusual) case of antipodal points (on opposite ends of the sphere).

The Haversine distance calculates the distance between two points on a sphere when traveling along the sphere. The values must be in radians. hsin also take a Boolean argument to specify whether the function should convert its output to radians.

The haversine formula is an equation important in navigation, giving great-circle distances between two points on a sphere from their longitudes and latitudes.It is a special case of a more general formula in spherical trigonometry, the law of haversines, relating the sides and angles of spherical triangles.
