I have a map which overlays Open Street Map data on imagery for Pennsylvania. As a baselayer to the roads (and eventually other layers) I have two baselayers - Blue Marble NG and USGS EROS 1ft imagery. I would like to be able to combine these two layers into a single base map object that switches automatically as the user zooms in since it makes no sense to view the 1ft imagery for the whole state or the Blue Marble imagery when you are zoomed in.
Ideally I'd like to do this on the client side as I'm pulling the imagery from two different sites.
