Bing Maps provides map imagery that users can integrate into their application. To allow clients to load and navigate the imagery as fast as possible, each map view is cut into individual map tiles. This topic contains information about the numbering system used to identify individual tiles.
A map view is comprised of a grid of tiles, numbered from left to right for each row. The table below shows the tile IDs for a map view that contains 5 tiles across and 4 tiles down.
0 | 1 | 2 | 3 | 4 |
5 | 6 | 7 | 8 | 9 |
10 | 11 | 12 | 13 | 14 |
15 | 16 | 17 | 18 | 19 |
The number of tiles in a map view varies depending on the zoom level of the map. If the zoom level is high (close to the ground), fewer tiles make up the map view. If the zoom level is low (farther away from the ground), more tiles are required to make up a map view.
Tile IDs are needed to construct URIs used to request map tiles from Bing Maps. The ImageryServiceClient.GetImageryMetadata Method returns tile URIs in the ImageryMetadataResult.ImageUri Property. If you want to retrieve a URL to a complete static map, use the ImageryServiceClient.GetMapUri Method instead.

| Tile IDs should not be confused with "quadkeys", which uniquely identify single tiles at particular levels of detail, and can be used as keys in common database B-tree indexes. For information about generating quadkeys, see the Bing Maps Tile System in the Bing Maps Articles. |
