TransDEM has this wonderful feature where it can create a set of UTM tiles containing the terrain data as a guide so that objects can be placed in the map with the correct spacial relationship. When the tile contains only water, the color used is a uniform teal and Trainz makes a fuss. I can go in a apply some noise to each tile to keep Trainz quiet but is there a way to have TransDEM do this at creation instead? Since it's only water, not much loss if those tiles get deleted but I'd like to keep the complete set.
