UTM

Bidirectional UTM-WGS84 converter for golang. It use logic from UTM python version by Tobias Bieniek

Usage

go get github.com/im7mortal/UTM

Convert a latitude, longitude into an UTM coordinate

    easting, northing, zoneNumber, zoneLetter, err := UTM.FromLatLon(40.71435, -74.00597, false)

Convert an UTM coordinate into a latitude, longitude.

    latitude, longitude, err := UTM.ToLatLon(377486, 6296562, 30, "V")

Since the zone letter is not strictly needed for the conversion you may also the northern parameter instead, which is a named parameter and can be set to either true or false. In this case you should define fields clearly(!). You can't set ZoneLetter or northern both.

    latitude, longitude, err := UTM.ToLatLon(377486, 6296562, 30, "", false)

The UTM coordinate system is explained on this Wikipedia page
