Geo Coding

[Darren Stoppler]

Does anyone know the best way to get latitude and longitued information for a given address for OpenStreetMaps?

Thanks

Hi Darren,

OpenStreetMaps does not expose geocoding / routing services support. You can use OpenStreet map provider with the BingMaps geocoding / routing.

Hi Andrey,

Does Microsoft charge for this?  Also, are there any code examples for this.

Thanks for your reply.

Hi Darren,

You should retrieve a Bing Maps key before using BingMaps Services. Find the details in this article.
The following sample code uses this key in BingApplicationId for assigning this.geoProvider.ApplicationId property:

private BingGeocodeProvider geoProvider;


// initialize BingGeocodeProvider

private void InitGeoProvider()

{

    this.geoProvider = new BingGeocodeProvider();

    this.geoProvider.ApplicationId = BingApplicationId;

    this.geoProvider.MapControl = radMap;

    this.geoProvider.GeocodeCompleted += new EventHandler<GeocodeCompletedEventArgs>(geoProvider_GeocodeCompleted);

}


private void Button_Click(object sender, RoutedEventArgs e)

{

    GeocodeRequest request = new GeocodeRequest();

    request.Query = this.textbox1.Text;


    // start geocode request

    this.geoProvider.GeocodeAsync(request);

}



// request complete

private void geoProvider_GeocodeCompleted(object sender, GeocodeCompletedEventArgs e)

{

    if (e.Response.Results != null && e.Response.Results.Count > 0)

    {

        Location location = e.Response.Results[0].Locations[0];


        // Show object according to found location

    }

}
