  I'd love to add a map to this! I work as an archaeological illustrator and would relish doing something like this. However, my times limited so it would probably have to be a basic plan with contours adapted from something existing. I'd probably end up doing it in adobe illustrator and post it up as a jpeg? A cross-section would be nicer - and more ambitious and time-consuming so I perhaps wouldn't attempt that just at the minute!  Tomohawk
