Hi,

I am asking for a little help. I am working on simple map app using layers toggling exactly as in Sandcastle example "Imagery Layers Manipulation". My question is how to modify the sample code when I want to remove the "BaseLayerOption" function and set "Bing Maps Aerial" like a classic baselayer.

I'd be grateful for any advice.

Check out this thread which has example code for constucting the base layer picker with whatever options you want and setting the default provider: [https://groups.google.com/d/msg/cesium-dev/2UYkQyA7amU/ULsyQSGbDowJ](https://groups.google.com/d/msg/cesium-dev/2UYkQyA7amU/ULsyQSGbDowJ)
