I'll at least put the 24bit 2048x2048 .TGA file in the download section of my site, its about 12MB. What I really want to do is create 6 tiles that cover the whole area with a 2048x2048 TGA terrain file for each but thats looking quite difficult at the moment as I need to find a way of accurately splitting up the DEM. Maybe if I create a 24bit TGA file of the whole thing and then slice it up into 6 but thats bound to require some resizing to make the tiles the right size and that will introduce inaccuracies... hmmmm
