Overlay OpenStreetMap and Yahoo Maps Imagery using Custom Tile Layers!

In the “Virtual Earth Silverlight: Using Tile Layers to Overlay Custom Map Imagery” article I showed you how to overlay your own Custom Map Imagery that you generated using the MapCruncher tool on top of the Map. Now, in this article I’ll show you what you need to know in order to overlay map imagery from other competing mapping services (OpenStreetMap, OpenAerialMap and Yahoo Maps). This allows you to easily build in functionality that allows your users to easily switch (with the click of a button or selection of a dropdown) which mapping service imagery is used to visualize the data in your application.
