rust-gpx

gpx is a library for reading and writing GPX (GPS Exchange Format) files. It uses the primitives provided by rust-geo to allow for storage of GPS data.

Example

extern crate gpx;

use std::io::BufReader;
use std::fs::File;

use gpx::read;
use gpx::{Gpx, Track, Waypoint};

fn main() {
    // This XML file actually exists — try it for yourself!
    let file = File::open("tests/fixtures/wikipedia_example.gpx").unwrap();
    let reader = BufReader::new(file);

    // read takes any io::Read and gives a Result<Gpx, Error>.
    let gpx: Gpx = read(reader).unwrap();

    // Each GPX file has multiple "tracks", this takes the first one.
    let track: &Track = &gpx.tracks[0];
    assert_eq!(track.name, Some(String::from("Example GPX Document")));

    // Each track will have different segments full of waypoints, where a
    // waypoint contains info like latitude, longitude, and elevation.
    let segment: &TrackSegment = &track.segments[0];

    // This is an example of retrieving the elevation (in meters) at certain points.
    assert_eq!(segment.points[0].elevation, Some(4.46));
    assert_eq!(segment.points[1].elevation, Some(4.94));
    assert_eq!(segment.points[2].elevation, Some(6.87));
}
