Function openrailwaymap_exporter::importer::overpass_importer::calculate_geometry_length

pub fn calculate_geometry_length(geometry: &[Coordinate]) -> f64

Calculate the total length of a sequence of coordinates by summing the distance between consecutive coordinates.

Arguments

• geometry - A slice of Coordinate values representing a sequence of connected points.

Examples

use openrailwaymap_exporter::importer::overpass_importer::Coordinate;
use openrailwaymap_exporter::importer::overpass_importer::calculate_geometry_length;

let geometry = vec![
    Coordinate { lat: 1.0, lon: 1.0 },
    Coordinate { lat: 2.0, lon: 1.0 },
    Coordinate { lat: 2.0, lon: 2.0 },
];

let length = calculate_geometry_length(&geometry);
assert_eq!(length, 221827.195);
