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has been superseded by GeoDistance.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.
DetailsDetails
- To use
, you first need to load the Geodesy Package using
. - A point
is expressed as a pair of numbers
. - Each coordinate latitude and longitude can be given in degrees, or as
, or
. - 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:
-
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.
