In spatialrisk: Calculating Spatial Risk

Haversine great circle distance

Description

Calculates the shortest distance between two points on the Earth's surface using the Haversine formula, also known as the great-circle distance or "as the crow flies".

Usage

haversine(lat_from, lon_from, lat_to, lon_to, r = 6378137)

Arguments

lat_from	Latitude of the starting point.
lon_from	Longitude of the starting point.
lat_to	Latitude of the destination point.
lon_to	Longitude of the destination point.
r	Radius of the Earth in meters (default = 6378137).

Details

The Haversine ('half-versed-sine') formula was published by R.W. Sinnott in 1984, although it has been known for much longer.

Value

Vector of distances in the same unit as r (default in meters).
