Super Light-Weight Utility Functions for Working with Universal Transverse Mercator
Usage
Check if EPSG Code Refers to UTM
const isUTM = require('utm-utils/src/isUTM');
isUTM(32619); // true
isUTM("32619"); // true
isUTM("EPSG:32619"); // true
isUTM("+proj=utm +zone=17 +ellps=WGS84 +datum=WGS84 +units=m +no_defs"); // true
isUTM("3857"); // false
Get Hemisphere from EPSG Code
const getHemisphere = require('utm-utils/src/getHemisphere');
getHemisphere('32617'); // "N"
Get Zone from EPSG Code
const getZone = require('utm-utils/src/getZone');
getZone('32617'); // 17
Get PROJ String from EPSG Code
const getProjString = require('utm-utils/src/getProjString');
getProjString('32617');
"+proj=utm +zone=17 +ellps=WGS84 +datum=WGS84 +units=m +no_defs"
Get EPSG Code from a PROJ.4 String
const getCodeFromProjString = require('utm-utils/src/getCodeFromProjString');
getCodeFromProjString("+proj=utm +zone=17 +ellps=WGS84 +datum=WGS84 +units=m +no_defs");
32617
getCodeFromProjString("+proj=utm +zone=16 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs +type=crs")

Get EPSG Code from ESRI Well-Known Text
const getCodeFromEsriWKT = require('utm-utils/src/getCodeFromEsriWKT.js');
getCodeFromEsriWKT(`PROJCS["WGS_1984_UTM_Zone_17N",GEOGCS["GCS_WGS_1984",...,UNIT["Meter",1.0]]`);
