SpheroidalDistance
As of Version 7.0, SpheroidalDistance has been superseded by GeoDistance.
SpheroidalDistance[pt1,pt2]
gives the distance between points pt1 and pt2 on Earth using the spheroidal model of the planet.
更多信息和选项
- To use SpheroidalDistance, you first need to load the Geodesy Package using Needs["Geodesy`"].
- A point pti 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:
-
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.
