@ Everyone : Thank you for your comments, I am pleased at the response for a first try.

@ Waldronate : You definitely shouldn't stop, its really good to see what can be achieved with Fractal Terrain Pro/Wilbur at such a scale. It looks amazing ... You don't perchance have the MDR file available do you? <grins> I would love to see how you did that and it would save me a lot of work!

Its exactly what I was trying to achieve, thank you so much for all the effort. Its nice to know I was on the right track heading to Wilbur to add the river detail and even more pleasing to see it looks great.

Is there any easy way to extract the river data from the MDR, so I can convert it to a vector form in Illustrator or some such ?

I kind of get the feeling that at this point, I leave the work in FTP and work up close in Wilbur for each section of the map that I am interested in adding detailed rivers to, before moving to the final phase of making it prettier in Photoshop / Illustrator.

Ok I am off to experiment some more with Wilbur!
