Domain-specific

• Flattening
  • Reference ellipsoid. The Geodetic Reference System 1980 specifies a semimajor axis and reciprocal flattening, from which the polar semiaxis and eccentricity follow.
• Haversine Formula
  • One degree at the equator. With \(\Delta\lambda=1^\circ=\pi/180\) and equal zero latitudes, \(a=\sin^2(\pi/360)\approx0.0000761524\), \(\delta=\pi/180\), and for \(R=6371.0088\) km, \(d\approx111.195\) km

    This sourceThe reference system whose defining parameters (a = 6378137 m, 1/f = 298.257222101) yield the arithmetic mean radius R1 = 6371.0088 km used in the worked example; the value is the IUGG mean radius, not a measured constant.
