Geocoding.Yandex

Geocoding.net library extension for working with Yandex geocoder. Yandex geocoder works well with the geography of Russia, Ukraine, Belarus, Turkey and other close countries.

The API returns latitude/longitude coordinates and normalized address information. This can be used to perform address validation, real time mapping of user-entered addresses, distance calculations, and much more.

Usage Example

Simple Example

IGeocoder geocoder = new YandexGeocoder("yandex-api-key");
IEnumerable<Address> addresses = await geocoder.GeocodeAsync("Tverskaya 4");
Console.WriteLine("Formatted: " + addresses.First().FormattedAddress); //Formatted: Россия, Москва, Тверская улица, 4
Console.WriteLine("Coordinates: " + addresses.First().Coordinates.Latitude + ", " + addresses.First().Coordinates.Longitude); //Coordinates: 55,758493, 37,613198

It can also be used to return address information from latitude/longitude coordinates (aka reverse geocoding):

IGeocoder geocoder = new YandexGeocoder("yandex-api-key");
IEnumerable<Address> addresses = await geocoder.ReverseGeocodeAsync(38.8976777, -77.036517);

Using Yandex Provider Specific Data

Find address by known city

YandexGeocoder geocoder = new YandexGeocoder(ApiKey);
IEnumerable<YandexAddress> addresses = await geocoder.GeocodeAsync("Tverskaya 4");
var moscowAddress = addresses.First(address=>address.City == "Moscow");
Console.WriteLine($"Country: {moscowAddress.Country}, City: {moscowAddress.City}, Postal Code: {moscowAddress.PostCode}");

Specify response language

var geocoder = new YandexGeocoder(ApiKey)
{
  Language = Language.Turkish
};

Available languages: Russian, Belarusian, Ukrainian, Turkish, English

Specify toponym (Only for reverse geocoding)

geocoder.Kind = Kind.Metro;

Possible values: House, Street, Metro, District, Locality

Specify search boundaries

Ignored when Kind is set to District

geocoder.Bounds = new Bounds(55.542312, 37.253144, 55.933075, 37.861323);

Specify the number of addresses in response

geocoder.Results = 30;

By default - 10

Specify the number of skipped addresses

geocoder.Skip = 4;
