Geographic/UTM Coordinate Converter

With this library, you can convert between geographic coordinates and Universal Transverse Mercator (UTM) coordinates, and the other way around.

Usage:

var utmgeoconv = require('utmgeoconv');

console.log(utmgeoconv.latLonToUtm(59.10776931, 11.40488332, 32)); // { x: 637715, y: 6554533 }
console.log(utmgeoconv.utmToLatLon(32, 'n', 637715, 6554533)); // { lat: 59.107769, lon: 11.404883 }

The library is using the unmodified source code* found in the Chuck Taylor Toolbox which clearly states :
