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:
privateconststring endPoint = "http://maps.google.com/maps/geo?q={0},{1}&output=xml&sensor=true&key=YOURKEY";
privatestaticstring 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 = newWebClient())
{
string xml = client.DownloadString(url);
XmlDocument doc = newXmlDocument();
doc.LoadXml(xml);
XmlNode node = doc.ChildNodes[1].FirstChild.ChildNodes[2].ChildNodes[0];
return node.InnerText;
}
}
It returns the address as a string.
