从 BingMap 中的经度和纬度获取位置名称

Question

我是一名 WP7 开发人员。我有一个位置的经度和纬度。无论如何，是否可以获取坐标定义的位置信息，即经度和纬度。 谢谢你！！

Answer 1

是的，您可以通过 Bing 地图 REST API 执行此操作，您需要执行反向地理编码。这是通过 GET 执行以下请求来完成的：

http://dev.virtualearth.net/REST/v1/Locations/47.64054,-122.12934?o=xml&key=BingMapsKey

它将返回 XML 格式的地址：

Answer 2

您可以利用 Microsoft 提供的 Web 服务，根据您提供的纬度和经度返回城市、州和国家/地区。

通过提供链接 http://msrmaps.com/TerraService2.asmx 在项目中创建 Web 服务引用

我已将该服务命名为 myTerraService

myTerraService.TerraServiceSoapClient client = new myTerraService.TerraServiceSoapClient();
        client.ConvertLonLatPtToNearestPlaceCompleted += new EventHandler<myTerraService.ConvertLonLatPtToNearestPlaceCompletedEventArgs>(client_ConvertLonLatPtToNearestPlaceCompleted);
        client.ConvertLonLatPtToNearestPlaceAsync(new myTerraService.LonLatPt { Lat = latitude, Lon = longitude });
    }

    void client_ConvertLonLatPtToNearestPlaceCompleted(object sender, myTerraService.ConvertLonLatPtToNearestPlaceCompletedEventArgs e)
    {
        string location = e.Result; // this string will have city, state, country
    }
