OBSOLETE GEODESY PACKAGE SYMBOL

SpheroidalDistance

As of Version 7.0,

has been superseded by GeoDistance.

gives the distance between points

and

on Earth using the spheroidal model of the planet.

A negative value for a coordinate indicates that the coordinate is South latitude or West longitude.

Note that the model is an approximation formula that only employs machine-precision computation. It is fairly accurate to distances of up to 10000 kilometers on the standard model of Earth.

	SemimajorAxis	6378.14	specify the length of the semimajor axis
	Eccentricity	0.081819	specify the value of the eccentricity

With the setting SemimajorAxis->length the length of the semimajor axis in the spheroidal model is assumed to be length kilometers.

With the setting Eccentricity->v the eccentricity in the spheroidal model is assumed to be v.
