UTMConversion

Convert between latitude/longitude and the UTM (Universal Transverse Mercator) coordinate systems. The conversion happens between a custom struct UTMCoordinate and CoreLocation's CLLocationCoordinate2D and CLLocation.

Requirements

• iOS 8.0+ / macOS 10.10+ / tvOS 9.0+ / watchOS 2.0+
• Xcode 8.1+
• Swift 3.0+

Installation

Carthage

To integrate UTMConversion into your Xcode project using Carthage, specify it in your Cartfile:

github "peterringset/UTMConversion" ~> 1.1

Usage

Convert to UTM

import CoreLocation
import UTMConversion

let coordinate = CLLocationCoordinate2D(latitude: 63.430493678423012, longitude: 10.394966844991798)
let utmCoordinate = coordinate.utmCoordinate()

let location = CLLocation(latitude: 63.430493678423012, longitude: 10.394966844991798)
let utmCoordinate2 = location.utmCoordinate()

Convert from UTM

import CoreLocation
import UTMConversion

let utmCoordinate = UTMCoordinate(northing: 7034313, easting: 569612, zone: 32, hemisphere: .northern)
let coordinate = utmCoordinate.coordinate()
let location = utmCoordinate.location()

Datum

It is possible to specify your own datum (polar and equitorial radius), the default value is WGS84, which is the latest revision of the WGS standard.

import CoreLocation
import UTMConversion

let utmCoordinate = UTMCoordinate(northing: 7034313, easting: 569612, zone: 32, hemisphere: .northern)
let datum = UTMDatum(equitorialRadius: 6378137, polarRadius: 6356752.3142)
let coordinate = utmCoordinate.coordinate(datum: datum)
