Once the tile source is defined it can be used to create a tile layer. By specifying the map bounds and zoom range of the tiles, we can save the map from requesting tiles in areas where we know there are none. The following code example shows how to add this tile layer to the map, by first defining a tile source which includes the URL to the tiles and the map bounds and zoom range of the tiles. This is an optional field which is useful in helping you remember the purpose of that key in the.
Application URL: The URL of the application. The generated tiles use a quadkey naming system and have been generated for the first 10 zoom levels of Bing Maps. For new accounts, follow the instructions in Creating a Bing Maps Account. For this example, an image of Hurricane Katrina which was sourced from the NASA/GSFC, Rapid Response team was broken up into a set of tiles using a tool called Microsoft MapCruncher. In order to add a tile layer to the map, you first need a source of map tile data. The following is an example of how to do this.
The simplest implementation of the TileLayer class is to set the mercator property to a TileSource that has a uriConstructor property set to a URL which uses one or more of the tile URL parameters to access map tiles, such as the quadkey value.
