Distance Between Points

This uses the haversine formula (by default) to calculate the great-circle distance between two points, i.e., the shortest distance over the earth's surface.

Usage

point_distance(a, b, ...)

Arguments

a

lon, lat coordinate of point 1

b

lon, lat coordinate of point 2

...

parameters passed to tectonicr::dist_greatcircle()

Value

units object giving the distance

Examples

berlin <- c(13.4, 52.517) # lon, lat
tokyo <- c(139.767, 35.7) # lon, lat
point_distance(berlin, tokyo)
#> 247.4037 [km]
