This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (utm-utils) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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")
26916

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]]`);
32617
