Hello, follow the address to get to my pages where I have done work like this. I have spent the last three months creating a huge model, which is why I haven't posted on the forum recently. If no dem terrain is available, you have to make your own, (dems are very low res anyway, and not much use for small scale work). Its best to work with greyscale images rather than dems, as you can manipulate greyscale easily in lots of programs. Your map indicates that you should be able to trace these contours in about a day. When you have created you model, you can also draw a mask of the water features, and using 'mixed materials', have 'real' water on your model. I have a flyby animation of one of my models in which the sun shimmers off the water. You cannot get your camera too low. Everything looks supprisingly 3d because of shadows on the original aerials, but below a certain angle it all goes flat. Please conatact me if you want more detailed information. I'll post a pic my latest model soon - found an unknown Roman road and associated bits using it. zoon@derby-vi-service.demon.co.uk
