Trait geo::algorithm::geodesic_distance::GeodesicDistance
source · [−]pub trait GeodesicDistance<T, Rhs = Self> {
fn geodesic_distance(&self, rhs: &Rhs) -> T;
}Expand description
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.
