SRTM/HGT reader

A performant DTM(srtm) reader for .hgt files in Rust.

Supported resolutions

• 0.5 angle second (SRTM05) <- not sure that's how it's called

• 1 angle second (SRTM1)

• 3 angle second (SRTM3)

• feel free to open an issue if you need more

Example

use srtm_reader::*;

let coord = Coord::new(13.3255424, 56.92856);
// we get the filename, that shall include the elevation data for this `coord`
let filename = coord.get_filename();
// load the srtm, .hgt file
// NOTE: to be able to load it, you'll need the actual file
let tile = srtm_reader::Tile::from_file(filename).unwrap();
// and finally, retrieve our elevation data
let elevation = tile.get(coord);

also, see cli example for a real-life one

[!NOTE] a great source of DEM data, .hgt files is Sonny's collection

Dependents

• fit2gpx-rs
• file an issue if yours could be listed as well

Disclaimer

this crate is a forked version of the srtm crate which hasn't been updated in 6 years, and the PR hasn't been merged either in a long time. I've needed 0.5 angle support and also some more convenience methods for fit2gpx-rs, and here we are.
