mgrs

Utility for converting between WGS84 lat/long and MGRS coordinates, spunoff from proj4js

Usage

npm install mgrs

ES6:

import { LLtoMGRS, MGRStoLL, MGRStoBBoxLL } from 'mgrs';

const mgrs = LLtoMGRS([-77.03650573264287, 38.89773371566278]);
const [long, lat] = MGRStoLL('18SUJ2339307399');
const boundingLatlong = MGRStoBBoxLL('18SUJ2339307399');

CommonJS:

const mgrs = require('mgrs');

const mgrs = mgrs.LLtoMGRS([-77.03650573264287, 38.89773371566278]);
const [long, lat] = mgrs.MGRStoLL('18SUJ2339307399');
const boundingLatlong = mgrs.MGRStoBBoxLL('18SUJ2339307399');
