Get definite City name in Google maps reverse geocoding

Question

Using the Google Maps Geocoding API, i\'m able to get the formatted address for a particular coordinate. To get the exact city name, I\'m doing the following:

Answer 1

So I was trying to figure this out today and I came to this solution if it helps anyone. Google maps comes with the Geocoder built in now so you just create a geocoder object once the API has loaded.

You can easily wrap that in a function and just return an object with the city, state, and postal code. This site was helpful in allowing me to see what the different 'types' mean: Reverse Geocoding

var geocoder = new google.maps.Geocoder,
    latitude = 28.54, //sub in your latitude
    longitude = -81.39, //sub in your longitude
    postal_code,
    city,
    state;
geocoder.geocode({'location': {lat:latitude, lng:longitude}}, function(results, status) {
  if (status === google.maps.GeocoderStatus.OK) {
    results.forEach(function(element){
      element.address_components.forEach(function(element2){
        element2.types.forEach(function(element3){
          switch(element3){
            case 'postal_code':
              postal_code = element2.long_name;
              break;
            case 'administrative_area_level_1':
              state = element2.long_name;
              break;
            case 'locality':
              city = element2.long_name;
              break;
          }
        })
      });
    });
  }
});

For what it's worth, I was looking for something similar and am trying https://plus.codes/

If you strip the encoded bit it yields a fairly consistent city, state, country name:

const extractCityName = latlng => {
  googleMapsClient.reverseGeocode({ latlng }, (err, response) => {
    if (!err) {
      return response.json.plus_code.compound_code.split(' ').slice(1).join(' ');
    }
  });
};


// examples: 

console.log(extractCityName(40.6599718,-73.9817292));
// New York, NY, USA

console.log(extractCityName(37.386052, -122.083851));
// Mountain View, CA, USA

console.log(extractCityName(51.507351, -0.127758));
// Westminster, London, UK

You need to look at the type of the result, not the absolute index in the array of results. Iterate through the results array looking for the entry which has the appropriate type. Looks like that would be:

• locality indicates an incorporated city or town political entity

But data may vary with region.

Looks like you want the entry with both the 'locality' and the 'political' types:

{
   "long_name" : "Mumbai",
   "short_name" : "Mumbai",
   "types" : [ "locality", "political" ]
}
