srtm

Go library for reading Shuttle Radar Topography Mission (SRTM) HGT files

package main

import (
	"github.com/jda/srtm"
	"log"
)

func main() {
	geo, err := srtm.ReadFile("srtm/testdata/S46W067.hgt")
	if err != nil {
		log.Fatal(err)
	}
	p := geo[30]
	log.Printf("Lat: %.4f, Lng: %.4f, Elevation: %d", p.Latitude, p.Longitude, p.Elevation)
}

Limitations

1. Until issue #3 is resolved, only 1-arcsecond tiles are supported.
