There has been some but it has dropped off of late (past two months has been slow). This is something that I plan to get stuck into again in a very short while tho. I have just got a lot on right now and I think the other admins have also - you need a high pain threshold to work on this project as its completely nuts.

The plan is to get GTS (the terrain app I write) to process up the base map to level one and output some files which can be used to render the whole base map. The idea right now is to try to output files that might be compatible with a basic terragen scene and then try to increase the complexity as we go forward.
