Usage #
Simple usage.
Default geodetic system is WGS84
import 'package:utm/utm.dart';
final utm = UTM.fromLatLon(lat: -30, lon: -150);
print('zone: ${utm.zone}');
print('N: ${utm.northing}');
print('E: ${utm.easting}');
print('lat: ${utm.lat}');
print('lat: ${utm.lon}');
final latlon = UTM.fromUtm(
easting: utm.easting,
northing: utm.northing,
zoneNumber: utm.zoneNumber,
zoneLetter: utm.zoneLetter,
);
print('lat: ${latlon.lat}');
print('lon: ${latlon.lon}');
