@ Ravs : I thought about drawing them in by hand, but, as it happens, I figured out what I was doing wrong with the overlay, so the next update should show the rivers properly with the projection I want to use. As for the coloring, I'm using the "Show Other Shader" feature instead of showing altitude, and using the climate overlay posted above. It doesn't follow the contours as much as the altitude shader does, but, as I mentioned, it still needs a bit of tweaking before it is finalized.

I haven't had much of a chance to work on this over the weekend as I'd hoped. We had some incidents at work that required my attention, but I'm on MY weekend now, so I should be able to work on this some. I've got a few more tweaks to work out, and I've got to make a final decision on presentation, but as it stands now, all systems are a go and I expect to have this wrapped up with plenty of time to spare.
