Trait geo::algorithm::geodesic_distance::GeodesicDistance

pub trait GeodesicDistance<T, Rhs = Self> {
    fn geodesic_distance(&self, rhs: &Rhs) -> T;
}

Determine the distance between two geometries on an ellipsoidal model of the earth.

This uses the geodesic measurement methods given by Karney (2013). As opposed to older methods like Vincenty, this method is accurate to a few nanometers and always converges.

Examples

use geo::prelude::*;
use geo::point;

// New York City
let p1 = point!(x: -74.006, y: 40.7128);

// London
let p2 = point!(x: -0.1278, y: 51.5074);

let distance = p1.geodesic_distance(&p2);

assert_eq!(
    5_585_234., // meters
    distance.round()
