Dynmap - Flat View?

Just wondering if there's a way to access a top-down flat version of the survival dynmap? I'm looking at the next addition to Shortunga and a top down view would help a lot in terms of choosing a suitable location and planning construction.

 

Having said that I guess I could always screen grab a normal Minecraft map .

 

I think we might be able to add a flat view option as well, but not up to me.
