Google’s maps API now supports reversed GEO lookup which allows you to find an address based on geo coordinates.  All you need is a latitude, a longitude and this handy method:

private const string endPoint = "{0},{1}&output=xml&sensor=true&key=YOURKEY";


private static string GetAddress(double latitude, double longitude)


  string lat = latitude.ToString(CultureInfo.InvariantCulture);

  string lon = longitude.ToString(CultureInfo.InvariantCulture);

  string url = string.Format(endPoint, lat, lon);


  using (WebClient client = new WebClient())


    string xml = client.DownloadString(url);

    XmlDocument doc = new XmlDocument();



    XmlNode node = doc.ChildNodes[1].FirstChild.ChildNodes[2].ChildNodes[0];

    return node.InnerText;



It returns the address as a string.
