Geotum is for converting to and from latitude/longitude pairs and UTM points.
// Converting to UTM (near Santa Cruz) let latitude = 37.0837 let longitude = -121.9981 let latLonCoordinate = LatLonCoordinate(latiudinalDegrees: latitude, longitudinalDegrees: longitude) UTMConverter(datum: .wgs84).utmCoordinatesFrom(coordinates: latLonCoordinate) // Converting to Lat Lon let utmCoordinate = UTMPoint(easting: 589048.6, northing: 4104627, zone: 10, hemisphere: .northern) UTMConverter(datum: .wgs84).coordinateFrom(utm: utmCoordinate)
As detailed below this library suffers from a common UTM conversion problem, namely the poles (which are not supported by UTM) and the Svalbard/Norway problem.
I am aware of these problems and plan to fix them shortly.
Another library GeodeticUTMConverter works but is no longer maintained. As I (@pducks32) have dealt with geodesy both academically and professionally I thought I would start my own library to handle the conversions.
Geotum is available through CocoaPods. To install it, simply add the following line to your Podfile:
