Thank you for the positive responses.
I don't mind writing something up, but it will be a few days before I can get to it as I am on my way out of town on business... sorry.
I also have no problem uploading my palette and the associated TransDEM custom mapping file to the DLS. Fair warning, though: I created my textures using the same file combination/formats as the original TransDEM textures, so my files exhibit all the same warnings. Obviously they work just fine, so if no gets hung up on the fact that they are not 100% error-free then all will be well. On the other hand, I would be very happy if one of you experienced content creators cleaned them up and re-issued them -- or maybe someone can teach me how to clean them up before release?
Last but not least, this technique will only work in TS2010 and TS12, as it requires you to use the 5m grid option... which as far as I know is only available in those versions.
