Examples

dd2dms

Convert a coordinate in decimal degrees (DD) to degrees, minutes and seconds (DMS).

import { dd2dms } from 'latlng-conv'
console.log(dd2dms(10.1234))
// => {degrees: 10, minutes: 7, seconds: 24.24}
console.log(dd2dms(10.1234, 'lat'))
// => {degrees: 10, minutes: 7, seconds: 24.24, direction: 'N'}
console.log(dd2dms(-10.1234, 'lng'))
// => {degrees: 10, minutes: 7, seconds: 24.24, direction: 'W'}

dms2dd

Convert a coordinate in degrees, minutes and seconds (DMS) to decimal degrees (DD).

import { dms2dd } from 'latlng-conv'
console.log(dms2dd({degrees: 10, minutes: 7, seconds: 24.24}))
// => 10.1234
console.log(dms2dd({degrees: 10, minutes: 7, seconds: 24.24, direction: 'N'}))
// => 10.1234
console.log(dms2dd({degrees: 10, minutes: 7, seconds: 24.24, direction: 'S'}))
// => -10.1234

format

Create a string representation of a coordinate

import { format } from 'latlng-conv'
console.log(format({degrees: 10, minutes: 7, seconds: 24.24}))
// => 10° 7' 24.24"
console.log(format({degrees: 10, minutes: 7, seconds: 24.24, direction: 'N'}))
// => 10° 7' 24.24" N

parse

Parse a coordinate string and extract degrees, minutes, seconds and direction from it.

import { parse } from 'latlng-conv'
console.log(parse('10° 7\' 24.24"'))
// => {degrees: 10, minutes: 7, seconds: 24.24}
console.log(parse('10° 0\' 0"'))
// => {degrees: 10, minutes: 0, seconds: 0}
console.log(parse('10° 7\' 24.24" N'))
// => {degrees: 10, minutes: 7, seconds: 24.24, direction: 'N'}
