go-dms

A small library for converting Decimal Degrees to Degrees, Minutes, Seconds coordinates

Efficiently converting coordinates between DD and DMS

Installation

go get -u github.com/KingAkeem/go-dms/dms

test.go:

package main

import (
    "github.com/KingAkeem/go-dms/dms"
    "fmt"
    "time"
    "log"
)

func main() {
    start := time.Now()
    dmsCoordinate, err := dms.NewDMS(dms.LatLon{Latitude: 2.21893, Longitude: 1.213905})
    if err != nil {
        log.Fatal(err)
    }
    fmt.Printf("DMS coordinates: %+v\n", dmsCoordinate.String()) 
    end := time.Now()
    fmt.Printf("Function took %f seconds.\n", end.Sub(start).Seconds())
}

>> go run test.go

Output:

    DMS coordinates:
    2°13'8.148000" N, 1°12'50.058000" E
    Function took 0.000049 seconds.

>> node index.js

Output:
