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/Gasoid/go-dms/dms"
    "fmt"
    "time"
    "log"
)

func main() {
    lat, lon, err := dms.NewDMS(2.21893, 1.213905)
    if err != nil {
        log.Fatal(err)
    }
    fmt.Printf("DMS coordinates:\n%+v, %+v\n", lat.String(), lon.String())
}

>> go run test.go

Output:

    DMS coordinates:
    2°13'8.148000" N, 1°12'50.058000" E

>> GOOS=js GOARCH=wasm go run -exec="$(go env GOROOT)/misc/wasm/go_js_wasm_exec" . (Compiling as WebAssembly module for Node, run command in the same directory as test.go)

dms-js

index.js:

var dms = require('dms-conversion');
var NanoTimer = require('nanotimer');
var timerObj = new NanoTimer();

var dmsTest = function() {
    var coords = new dms.default(2.21893, 1.213905);
    console.log('DMS Coordinates: ' + coords.toString());
    return coords;
};

var seconds = timerObj.time(dmsTest, "", 's')
console.log('Function took ' + seconds + ' seconds.');

>> node index.js

Output:

    DMS Coordinates: 2°13′8.147999999999422″ N, 1°12′50.058″ E
    Function took 0.001828968 seconds.

formatcoords

index.js:
