Distance between two points on a spheroid

Source: R/spheroid_dist.R

Calculate the distance between two points on the surface of a spheroid using Vincenty's formula. This function can be used when GIS libraries for calculating distance are not available.

spheroid_dist(p1, p2)

Arguments

p1

coordinates of the first point in decimal degrees (LON, LAT)

p2

coordinates of the second point in decimal degrees (LON, LAT)

Value

numerical vector with distance between two locations (in kilometers)

Examples

 p1 = c(18.633333, 54.366667) # longitude and latitude for Gdansk, PL
 p2 = c(17.016667, 54.466667) # longitude and latitude for Slupsk, PL
 spheroid_dist(p1, p2)
