Usage

Example usage of this file with Cesium and OpenLayers can be found within https://github.com/codice/ddf

var usng = require('usng.js');

var converter = new usng.Converter();

var usngCoord = converter.LLBboxtoUSNG(north, south, east, west);

var utmCoord = converter.LLtoUTM(lat, lon, utmcoords, zone);

var usngCoord = converter.LLtoUSNG(lat, lon, precision);

var llCoord = converter.UTMtoLL(UTMNorthing, UTMEasting, UTMZoneNumber, accuracy);

var utmCoord = converter.USNGtoUTM(zone,letter,sq1,sq2,east,north,ret);

var llCoord = converter.USNGtoLL(usngStr_input, getCenter);

var mgrsCoord = converter.LLtoMGRS(lat, lon, precision);
