Trait RhumbLength

Source

pub trait RhumbLength<T, RHS = Self> {
    // Required method
    fn rhumb_length(&self) -> T;
}

👎Deprecated since 0.29.0: Please use the line.length::<Rhumb>() via the Length trait instead.

Expand description

Determine the length of a geometry assuming each segment is a rhumb line.

Note: this implementation uses a mean earth radius of 6371.088 km, based on the recommendation of the IUGG

fn rhumb_length(&self) -> T

👎Deprecated since 0.29.0: Please use the line.length::<Rhumb>() via the Length trait instead.

Determine the length of a geometry assuming each segment is a rhumb line.

§Units

return value: meters

§Examples

use geo::prelude::*;
use geo::LineString;

let linestring = LineString::<f64>::from(vec![
    // New York City
    (-74.006, 40.7128),
    // London
    (-0.1278, 51.5074),
]);

let length = linestring.rhumb_length();

assert_eq!(
    5_794_129., // meters
    length.round()
);
