Expand description

Calculates the Geodesic Distance between between two Points

\param a first geodesic parameter. \param b second geodesic parameter. \param rf third geodesic parameter. \param lat1 Latitude of first Point. \param lon1 Longitude of first Point. \param lat2 Latitude of second Point. \param lon2 Longitude of second Point.

\return the calculated Geodesic Distance.

\sa gaiaEllipseParams, gaiaGreatCircleDistance, gaiaGreatCircleTotalLength, gaiaGeodesicTotalLength

\note the returned distance is expressed in Kilometers. \n the Geodesic method is much more accurate but slowest to be calculated.
