必应地图到医院

Question

我正在尝试使用必应地图API(用于Windows 8 Metro应用程序)来获取印度特定城市的所有医院。不过，我找不到细节。下面是尝试过的两种方法

1. 使用NearbyVenueCollection类 NearbyVenueOptions options =新NearbyVenueOptions(loc，10000)；NearbyVenueCollection nearbyVenues = null；} catch (异常){} if (nearbyVenues != null & nearbyVenues.Count > 0) { foreach (var nearbyVenue in nearbyVenues) { if (nearbyVenue.Metadata.VenueType == VenueType.Hospital.ToString()) { string name = nearbyVenue.Metadata.Name；}}

这并不是提供所需的细节。

1. 使用Bing空间数据服务

下面是代码片段

////Create the Bing Spatial Data Services request to get nearby POI
string findNearbyPOIRequest = "http://spatial.virtualearth.net/REST/v1/data/            f22876ec257b474b82fe2ffcb8393150/ NavteqNA/NavteqPOIs? spatialfilter=nearby("
+ loc.Latitude + "," + loc.Longitude + "," + 1000 + ")"
+ "&$filter=EntityTypeID%20EQ%20'" + "8060" + "'&               $select=EntityID,DisplayName,__Distance,Latitude,Longitude,AddressLine,         Locality,AdminDistrict,PostalCode,Phone&$top=20"
+ "&key=" + BingCredentials;


Uri uri = new Uri(findNearbyPOIRequest);
WebRequest request = WebRequest.Create(uri);

// GetResponseAsync() returns immediately after the header is ready 
WebResponse response = await request.GetResponseAsync();
Stream inputStream = response.GetResponseStream();

XDocument doc = XDocument.Load(inputStream);
XNamespace m ="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata";
XNamespace d = "http://schemas.microsoft.com/ado/2007/08/dataservices";
MapLayer pushpinLayer = new MapLayer();
pushpinLayer.Name = "Push Pin Layer";

var elements = from nodes in doc.Descendants(m + "properties")
               select new
               {
                   Name = nodes.Element(d + "DisplayName").Value,
                   Latitude = nodes.Element(d + "Latitude").Value,
                   Longitude = nodes.Element(d + "Longitude").Value,
                   Address = nodes.Element(d + "AddressLine").Value,
               };

然而，我并没有得到印度城市所需的详细信息。有人能帮我弄清楚需要做些什么才能得到正确的细节吗？

Answer 1

场地地图仅是必应地图有室内平面图的地点。我不知道在印度有任何医院可以作为场地地图。必应空间数据服务中感兴趣的数据仅在北美和欧洲提供。在印度寻找地点的最佳选择是使用Bing地图SOAP搜索服务。
