format decimal lat/lon coords into degrees/minutes/seconds formats (like DMS).
npm install formatcoords
A simple and flexible tool to format decimal lat/lon coordinates into degrees/minutes/seconds formats (like DMS), using a moment.js-like API.
For geo hipsters that think that 48° 54′ 16.016″ S 71° 0′ 56.250″ W looks way more awesome than -48.9044488,-71.015625.
``
npm install formatcoords
`
var formatcoords = require('formatcoords');
formatcoords(40.76,-73.984).format();
//40° 45′ 36.000″ N 73° 59′ 2.400″ W
#### parsing
The `formatcoords(coord1[, coord2, lonlat])` method accepts decimal lat/lon coordinates in several formats :`
- formatcoords([lat, lon])`: an array of floats.`
- formatcoords([lon, lat], true)`: an array of floats. First longitude, then latitude. Useful for use with GeoJSON, for example.`
- formatcoords(lat, lon)` : floats.`
- formatcoords(lon, lat, true)` : floats. First longitude, then latitude. Useful for use with GeoJSON, for example.`
- formatcoords('latlon')` : `latlon` is a string in "lat,lon" format.`
- formatcoords({lat: lat, lng: lon}` an object with `lat` and `lng` properties (Leaflet LatLng object)
#### formatting
`
var coords = formatcoords(27.725499,-18.024301);
`
coords.format(format, {options})
Default output format is DMS (degrees minutes seconds), with a space to separate lat and lon, and 5 decimal places :
`
coords.format()
//27° 43′ 31.796″ N 18° 1′ 27.484″ W

Custom format example with additional options
`
coord.format('DD MM ss X', {latLonSeparator: ', ', decimalPlaces: 0);
//35° 43′ 49″ S, 86° 1′ 55″ E
