UTM dart

Lat Lon and UTM bidirectional converter.
translate from Python UTM library

Support Geodetic System

  • WGS84 (default)
  • GRS80
  • Bessel

The UTM coordinate system is explained on this Wikipedia page.

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}');

Use specific geodetic system

UTM.fromLatLon(lat: -30, lon: -150, type: GeodeticSystemType.bessel);
UTM.fromUtm(
  easting: utm.easting,
  northing: utm.northing,
  zoneNumber: utm.zoneNumber,
  zoneLetter: utm.zoneLetter,
  type: GeodeticSystemType.grs80,
);
