Geocodeservice of bingmap performs geographic location retrieval and reverse retrieval-Background implementation

1. Add a web service reference for geocodeservice

Geocodeservice is a Web Service released by the WCF technology, the map encoding Service provides a valid physical address to match the corresponding map address (both geographic longitude and latitude coordinates) on the map) the physical address path is reversely matched with geographic longitude and latitude coordinates. To use the service, you need to add a web service reference for the Service (http://dev.virtualearth.net/webservices/v1/geocodeservice/GeocodeService.svc), as shown in

2. Obtain the latitude and longitude code through the address:

<span style="font-size:14px;">GeocodeServiceClient geocodeService = new GeocodeServiceClient();GeocodeRequest geocodeRequest = new GeocodeRequest();geocodeRequest.Credentials = new Credentials();geocodeRequest.Credentials.ApplicationId = "Arn2694QD8zXQJGN_IgecLbotcSVT1gTyRFfNSdPsIOO - yWjkkZRbwKcNEpCfelq";geocodeRequest.Query = sAddress;ConfidenceFilter[] filters = new ConfidenceFilter[1];filters[0] = new ConfidenceFilter();filters[0].MinimumConfidence = Confidence.Low;GeocodeOptions geocodeOptions = new GeocodeOptions();geocodeOptions.Filters = filters;geocodeRequest.Options = geocodeOptions;GeocodeResponse geocodeResponse = new GeocodeResponse();geocodeResponse = geocodeService.Geocode(geocodeRequest);if (geocodeResponse.Results != null){int iLength = geocodeResponse.Results.Length;if (iLength >= 1){string sConfidence = geocodeResponse.Results[0].Confidence.ToString();if (sConfidence == "High"){string sState = geocodeResponse.Results[0].Address.AdminDistrict;string sCity = geocodeResponse.Results[0].Address.Locality;string sZip = geocodeResponse.Results[0].Address.PostalCode;string sLat = geocodeResponse.Results[0].Locations[0].Latitude.ToString();string sLon = geocodeResponse.Results[0].Locations[0].Longitude.ToString();string sqlExist = "select * from mapping_geodata_boundary where code='NJ0415' and boundary.STContains(geometry::STGeomFromText('POINT(" + sLon + " " + sLat + ")', 0))=1";DataTable dtExist = _dataAccess.GetTables(sqlExist);if (dtExist.Rows.Count > 0){//Updatestring sqlUpdate = "update mapping_parcels set city_state_zip=owner_citystate where city is null and fid=" + id;_dataAccess.ExcuateSQL(sqlUpdate);}}}}}</span>

3. Obtain the address code through latitude and longitude:

<span style="font-size:14px;">ReverseGeocodeRequest reverseGeocodeRequest = new ReverseGeocodeRequest();reverseGeocodeRequest.Credentials = new Credentials();reverseGeocodeRequest.Credentials.ApplicationId = "Arn2694QD8zXQJGN_IgecLbotcSVT1gTyRFfNSdPsIOO - yWjkkZRbwKcNEpCfelq";Location point = new Location();point.Latitude = double.Parse(lat);point.Longitude = double.Parse(lon);reverseGeocodeRequest.Location = point;GeocodeServiceClient geocodeService = new GeocodeServiceClient("BasicHttpBinding_IGeocodeService");GeocodeResponse geocodeResponse = geocodeService.ReverseGeocode(reverseGeocodeRequest);if (geocodeResponse.Results != null){int iLength = geocodeResponse.Results.Length;if (iLength >= 1){string sConfidence = geocodeResponse.Results[0].Confidence.ToString();if (sConfidence == "Medium" || sConfidence == "High"){string sAddress = geocodeResponse.Results[0].DisplayName;if (sAddress.Contains("'")){sAddress = sAddress.Replace("'", "''");}string sStreetName = geocodeResponse.Results[0].Address.AddressLine;//string sState = geocodeResponse.Results[0].Address.AdminDistrict;string sCity = geocodeResponse.Results[0].Address.Locality;string sZip = geocodeResponse.Results[0].Address.PostalCode;string sLat = geocodeResponse.Results[0].Locations[0].Latitude.ToString();string sLon = geocodeResponse.Results[0].Locations[0].Longitude.ToString();string sMatchCodes = geocodeResponse.Results[0].MatchCodes[geocodeResponse.Results[0].MatchCodes.Length - 1].ToString();string sqlExist = "select * from mapping_geodata_boundary where code='NJ0415' and boundary.STContains(geometry::STGeomFromText('POINT(" + sLon + " " + sLat + ")', 0))=1";DataTable dtExist = _dataAccess.GetTables(sqlExist);if (dtExist.Rows.Count > 0){//Updatestring sqlUpdate = "update mapping_parcels set shape_street_name='" + sStreetName+ "',shape_city='" + sCity + "',shape_address='" + sAddress+ "',shape_zip='" + sZip + "',shape_matchcode='" + sMatchCodes + "' where fid=" + id;_dataAccess.ExcuateSQL(sqlUpdate);}}}}</span>
