ImageryServiceClient.GetImageryMetadata Method

Retrieves metadata for imagery hosted by Bing Maps.

Syntax

public ImageryMetadataResponse GetImageryMetadata(ImageryMetadataRequest request)

Public Function GetImageryMetadata(ByVal request As ImageryMetadataRequest) As ImageryMetadataResponse

Parameters

Return Value

Returns an ImageryMetadataResponse Class, which contains an ImageryMetadataResult Class array.

Remarks

The ImageryProviders property contains the imagery data providers for the map style specified in the VEImageryMetadataOptions.MapStyle Property. If imagery metadata is needed for two different map styles, two GetImageryMetadata requests need to be made.

Example

private void RequestImageryMetadata()
{
string Results = "";
try
{
// Set a Bing Maps key before making a request
string key = "Bing Maps Key";

ImageryService.ImageryMetadataRequest metadataRequest = new ImageryService.ImageryMetadataRequest();

// Set credentials using a valid Bing Maps Key
metadataRequest.Credentials = new ImageryService.Credentials();
metadataRequest.Credentials.ApplicationId = key;

// Set the imagery metadata request options
ImageryService.Location centerLocation = new ImageryService.Location();
centerLocation.Latitude = 47.65;
centerLocation.Longitude = -122.24;

metadataRequest.Options = new ImageryService.ImageryMetadataOptions();
metadataRequest.Options.Location = centerLocation;
metadataRequest.Options.ZoomLevel = 10;

metadataRequest.Style = ImageryService.MapStyle.AerialWithLabels_v1;

// Make the imagery metadata request
ImageryService.ImageryServiceClient imageryService
= new ImageryService.ImageryServiceClient("BasicHttpBinding_IImageryService");
ImageryService.ImageryMetadataResponse metadataResponse = imageryService.GetImageryMetadata(metadataRequest);

Results = "The image requested was created between " + metadataResponse.Results[0].Vintage.From.ToString() + " and " + metadataResponse.Results[0].Vintage.To.ToString();

}
catch (Exception ex)
{
Results = "An exception occurred: " + ex.Message;

}
}
