Virtual Earth Silverlight Map Control CTP – Put Scalable Content on the Map
In the previous post I showed how to position Silverlight UIElements at a Location to create pushpins with the Virtual Earth Silverlight Map Control CTP. You can also position content in a scalable manner using the MapLayer.MapRectangle attached property. For example, the following code will position a scalable video on the Map by specifying the bounding box in LocationRect coordinates – by specifying the Location of the corners of the bounding box. The video is from the MIX’09 conference and it is being mapped to the roof of the Venetian:
<m:Map Mode="Aerial" Center="36.12135,-115.165998" ZoomLevel="17">
<m:Map.Children>
<MediaElement Source="http://mschannel9.vo.msecnd.net/o9/mix/09/wmv/key01.wmv" m:MapLayer.MapRectangle="36.122098,-115.167745,36.120414,-115.164390" Opacity="0.75"/>
</m:Map.Children>
</m:Map>
Here is a screenshot and a link to the running sample:

Notice as you zoom in and out the video will scale with the Map since it was mapped to the bounding box. This can be done with any Silverlight UIElement including images and other user controls. Here are 2 screenshots showing how the video scales with the Map as you zoom in:
