Pairwise Vincenty distance

Source: R/extendr-wrappers.R
ga_dist_vincenty_pairwise.Rd

The Vincenty formula computes the geodesic distance between two points on an ellipsoidal model of the earth. Returns NA if the algorithm fails to converge.

Usage

ga_dist_vincenty_pairwise(origin, dest)

Arguments

origin

a GeoArrow point array of origin points

dest

a GeoArrow point array; length 1 or the same length as origin

Value

a double vector of distance values in meters

References

Examples

# Raleigh to Charlotte, and Raleigh to Wilmington
