calcVinSph {MGDrivE}

Calculate Geodesic Distance - Vincenty Sphere Method

Description

This function calculates geodesic distance using the Vincenty sphere method.

Usage

calcVinSph(latLongs, r = 6378137)

Arguments

latLongs

Two column matrix of latitudes/longitudes

r

Earth radius. Default is WGS-84 radius

Examples

# two-column matrix with latitude/longitude, in degrees
latLong = cbind(runif(n = 5, min = 0, max = 90),
                runif(n = 5, min = 0, max = 180))

# Vincenty Sphere  distance formula
distMat = calcVinSph(latLongs = latLong)
