If you would like to create a web based app open Visual Studio and create a new ASP.NET Web Application called BoundedTileLayer. Since the APIs are nearly identical, the only differences between the Windows Store and web app will be the main HTML page that loads in the script references needed for the app. The Windows Store app will reference a local copy of the Bing Maps API while the web app will be loading in a cloud hosted version of the Bing Maps API.
The main difference is that we will be using different JavaScript references to load the map control into the page. Both APIs are nearly identical, but there are a couple of minor differences. The web based app will make use of the Bing Maps AJAX Control Version 7 while the Windows Store app will make use of the Bing Maps for Windows Store Apps SDK. In this blog post you have the choice of creating a web or a Windows Store app. Also, we will make it so that this tile layer can support tile services that use quadkey, x y and zoom, or bounding box naming conventions for retrieving tiles.įull source code for this blog post can be found in the MSDN Code Samples here.
In this blog post we will cover how to create a custom tile layer in Bing Maps AJAX Control Version 7 and the Bing Maps for Windows Store Apps JavaScript map controls that is limited to a bounding box area and a zoom level range. In addition, we will also make it so that this tile layer can support tile services that use quadkey, x y and zoom, or bounding box naming conventions for retrieving tiles. In this blog post we are going to see how we can create a custom tile layer in Bing Maps AJAX Control Version 7 and the Bing Maps for Windows Store Apps JavaScript map controls that is limited to a bounding box area and a zoom level range. Instead of providing properties for restricting the region the tile layer renders in, it gives us the ability to provide a callback function where we can add advanced functionality for loading tile layers. In the Bing Maps AJAX Control Version 7 and Bing Maps for Windows Store Apps JavaScript map controls tile layers are designed to be much more customizable. Many of these controls provide methods for limiting tile layers to a specific bounding box or zoom level range. In this blog post, I will show you how to create bounded tile layers in Bing Maps AJAX Control Version 7 and the Bing Maps for Windows Store Apps control.īing Maps supports tile layers in all of its map controls and has done so for a long time.
Otherwise you will end up with a lot of extra requests being made to your tile service for nothing. If this is the case then you will want to limit the loading of tiles in your app to that area. Depending on the type of data you are displaying as a tile layer, you may find that it is localized to a small part of the world. Tile layers are a great way to visualize a lot of data on a map and still have good performance.
