Reverse Geocoding

This example demonstrates reverse geocoding of coordinates to addresses.

Read the documentation.

JavaScript

function initMap() {
  var map = new google.maps.Map(document.getElementById("map"), {
    zoom: 8,
    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[0]) {
        map.setZoom(11);
        var marker = new google.maps.Marker({
          position: latlng,
          map: map
        });
        infowindow.setContent(results[0].formatted_address);
        infowindow.open(map, marker);
      } else {
        window.alert("No results found");
      }
    } else {
      window.alert("Geocoder failed due to: " + status);
    }
  });
}
