Reverse Geocoding

This example demonstrates reverse geocoding of coordinates to addresses.

Read the documentation or view this example full screen.

    center: {lat: 40.731, lng: -73.997}
  });
  var geocoder = new google.maps.Geocoder;
  var infowindow = new google.maps.InfoWindow;

  document.getElementById('submit').addEventListener('click', function() {
    geocodeLatLng(geocoder, map, infowindow);
  });
}

function geocodeLatLng(geocoder, map, infowindow) {
  var input = document.getElementById('latlng').value;
  var latlngStr = input.split(',', 2);
  var latlng = {lat: parseFloat(latlngStr[0]), lng: parseFloat(latlngStr[1])};
  geocoder.geocode({'location': latlng}, function(results, status) {
    if (status === 'OK') {
      if (results[1]) {
        map.setZoom(11);
