Bing Maps Get Imagery Metadata API retirement

Bing Maps Get Imagery Metadata API is deprecated and will be retired. Free (Basic) account customers can continue to use Bing Maps Get Imagery Metadata API until June 30th, 2025. Enterprise account customers can continue to use Bing Maps Get Imagery Metadata API until June 30th, 2028. To avoid service disruptions, all implementations using Bing Maps Get Imagery Metadata API will need to be updated to use Azure Maps Get Map Tile API by the retirement date that applies to your Bing Maps for Enterprise account type. For detailed migration guidance, see Migrate Bing Maps Get Imagery Metadata API.

Azure Maps is Microsoft's next-generation maps and geospatial services for developers. Azure Maps has many of the same features as Bing Maps for Enterprise, and more. To get started with Azure Maps, create a free Azure subscription and an Azure Maps account. For more information about azure Maps, see Azure Maps Documentation. For migration guidance, see Bing Maps Migration Overview.

The response returned by an Imagery Metadata URL request contains a resource that provides imagery metadata information. If the metadata requested is for Birdseye imagery, a Birdseye Metadata resource is returned. For other types of imagery, an Imagery Metadata resource is returned. This topic contains descriptions of the information elements in these resources, followed by JSON and XML examples.

For more information about the common response syntax for the Bing Maps REST Services, see Common Response Description.

Common Imagery Resource Fields

The following fields are used in the Imagery Metadata, the Birdseye Metadata, and Streetside Metadata resources.

JSON	XML	Type	Description
`imageUrl`	`ImageUrl`	`URI`	One of the following: A URL template for an image tile if a specific point is specified. A general URL template for the specified imagery set. Note: For more information about the URI placeholder fields that may appear in the image tile, see Understanding the Image URL Placeholders section below.
`imageUrlSubdomains`	`ImageUrlSubdomains`	`string`	One or more URL subdomains that may be used when constructing an image tile URL.
`imageWidth`	`ImageWidth`	`integer`	The width of the image tile.
`imageHeight`	`ImageHeight`	`integer`	The height of the image tile.
`vintageStart`	`VintageStart`	`DateTime`	The earliest date found in an imagery set or for a specific imagery tile.
`vintageEnd`	`VintageEnd`	`DateTime`	The latest date found in an imagery set or for a specific imagery tile.
`zoomMin`	`ZoomMin`	`integer`	The minimum zoom level available for this imagery set.
`zoomMax`	`ZoomMax`	`integer`	The maximum zoom level available for this imagery set.

Birdseye Metadata Resource Fields

These fields are only used only by the Birdseye Metadata resource.

JSON	XML	Type	Description
`orientation`	`Orientation`	`double`	The orientation of the viewport for the imagery metadata in degrees where 0 = North [default], 90 = East, 180 = South, 270 = West.
`tilesX`	`TilesX`	`integer`	The horizontal dimension of the imagery in number of tiles, at zoom level zoomMax. To determine the approximate number of tiles at a lower zoom level, divide tileX by two (rounding down) for each lower zoom level between zoomMax and the desired level. To determine the exact number of tiles at a different zoom level, make another metadata call specifying the desired zoom level.
`tilesY`	`TilesY`	`integer`	The vertical dimension of the imagery in number of tiles, at zoom level zoomMax. To determine the approximate number of tiles at a lower zoom level, divide tileY by two (rounding down) for each lower zoom level between zoomMax and the desired level. To determine the exact number of tiles at a different zoom level, make another metadata call specifying the desired zoom level.

Streetside Metadata Resource Fields

Along with the above Common Imagery Resource fields, the Streetside Metadata resources contains the following fields. The order of these fields may differ between XML and JSON responses.

JSON	XML	Type	Description
`lat`	`Latitude`	`double`	The latitude of the specified center point.
`lon`	`Longitude`	`double`	The longitude of the specified center point.
`pi`	`Pitch`	`double`	The pitch is the degree from `-90`° (facing down) to `90`° (facing up) which the image was taken. When the pitch is `0`°, the image was take facing directly forward.
`ro`	`Roll`	`double`	Roll is how much the image is tilted when it was taken. A roll of 0° means the image was created along the East/West axis.

Note

The values for pitch, roll, and heading in the Streetside Metadata response are values for the camera that captured the image. Positive angles indicate clockwise rotation, negative angles indicate a counterclockwise rotation.

Heading, Pitch, and Roll

For more information, see how heading (yaw), roll, and pitch are used in Aeronautics and Flight on Wikipedia.

Understanding the Image URL Placeholders

When you request imagery metadata, the image URL field returned in the response specifies a map tile. This map tile can contain one or more of the following placeholders.

URI placeholder	Description
{culture}	The culture of the map. The culture value determines the language that is used to display text. For a list of cultures that are supported by the Imagery API, see Culture Parameter.
{quadkey}	The quadkey of the tile. For information about quadkeys, see bBing Maps Tile System.
{subdomain}	The sub-domain to use to retrieve tiles to allow maximum performance for network calls. The value values are `t0`, `t1`, `t2`, or `t3`.
{tileId}	TileId is an index from 0 to `(tilesX * tilesY) - 1` indicating a specific tile in the scene. 0 is top left corner and tiles are numbered in row order. So increasing values go left to right and then top to bottom.
{zoom}	The zoom level of the map.

Examples

The following examples show the resources returned by the Imagery Metadata API.
