Mwahahahah I have it !!!
Thanks to Monks, a free terragen to tif converter, a few custom programs to get to raw and image magick to PNG16 we have what IM reckons to be png16 files.
I havent checked them and I know the scaling is not perfect but heres some links. Again - they are big so only get em if you have to - and I wouldnt rely on saving the file from your browser window, use its "save link as" option or else it might drop it from 16bit to 8bit.
World
Region
Monks reckons that the Region range = -3607.4 to 8142.3 ft. I have scaled it so that it takes the full white range for maximum accuracy so you will have to adjust accordingly. And I have clipped it a bit so if the max range is within the border then it will be out also. The image size is 6144x5120 which is 6x5 x 1024x1024 tiles cut to the edges of the Torq's array.
