SpheroidalDistance

• To use SpheroidalDistance, you first need to load the Geodesy Package using Needs["Geodesy`"].

• A point pt_i is expressed as a pair of numbers {latitude, longitude}.

• Each coordinate latitude and longitude can be given in degrees, or as {degrees, minutes}, or {degrees, minutes, seconds}.

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

• Distances are returned in kilometers.

• 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.

• The following options can be given:

• 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.
