haversine: Haversine distance between two points on the Earth's surface

In rtlemos/scallops: Lemos and Sanso' (2012) model, edited for speed

Description

Haversine distance between two points on the Earth's surface

Usage

haversine(s_i, s_j)

Arguments

s_i	Point i, identified by latitude and longitude
s_j	Point j

Value

Distance between points i and j, in km

Examples

d1 = haversine(s_i = list(lat = 0, lon = 10), s_j = list(lat = 0, lon = 11))
d2 = haversine(s_i = list(lat = 10, lon = 10), s_j = list(lat = 11, lon = 10))
abs(2 * pi * 6371 / 360 - d1) < 0.001
abs(2 * pi * 6371 / 360 - d2) < 0.001
