coordinate-altitude
fetch altitude/elevation data for a coordinate of planet Earth
example
after cargo add coordinate_altitude
, do
use coordinate_altitude::*;
fn main() {
// coordinate as a tuple
let coord: (f64, f64) = (34.324, 1.88832);
// coordinate as a `Coord`
let coord: Coord = coord.into();
// and finally fetch altitude for `coord`
let coord: Option<Coord> = coord.fetch_altitude();
println!("coordinate: {coord:?}");
}
see examples for more
warning!
open-elevation is only 6 decimal places accurate
eg.: 32.324325435
will become 32.324325
dependencies
- json (de)serialization: serde, serde_json
- GET/POST requests: ureq
- Elevation data source: open-elevation
lib.rs
:
Get altitude/elevation data for geographical coordinates of planet Earth
WARNING
every latitude, longitude data will be rounded to 6 decimal places accuracy by open-elevation api
Usage
use coordinate_altitude::*;
// fetch altitude for a single `Coord`
// could also be a tuple for example, and later converted into Coord
// let coord: (f64, f64) = (34.324, 1.88832);
// let coord: Coord = coord.into();
// coordinate as a `Coord`
let coord = Coord::new(34.324, 1.88832);
// and finally fetch altitude for `coord`
let coord: Option<Coord> = coord.fetch_altitude();
println!("coordinate: {coord:?}");
// add altitude for a `Vec<Coord>`
let mut coords: Vec<Coord> = vec![
(58.2926289, 134.3025286).into(), // Sheep Mountain
(7.4894883, 80.8144869).into(), // Sri Lanka
Coord::new(47.0745464, 12.6938825), // Großglockner
];
add_altitude(&mut coords);
println!("coordinates: {coords:#?}");
- you could also add altitude for a single
Coord
- or fetch altitude for a
Vec<Coord>
- you can easily
impl From<YourWayOfStoringCoordinates> for Coord
, see tests/integ.rs
