Something I've been playing with for a few months - using channel and valley relationships in different terrain units to infer relative elevation.
Low order --> high order = upstream --> downstream = higher elevation --> lower elevation. While many of the terrain units could be placed on a relative scale, others are speculative. So this is partly artistic speculation rather than hard science. Still, most of the observed relationships seem to fit the model. I also creatively blurred things to soften the transitions. Pixel values are relative, not absolute. Relative Elevation Model of Sikun Labyrinthus, Titan:

That is a beautiful image Mike. (you're well on your way to creating a Google map of Titan!)

Yes, a very nice image and an interesting idea.

Very pretty indeed, and with the potential to link to the inevitably incomplete absolute elevation control that Cassini will leave us with, this could become an extremely useful resource.

Interesting idea... Perhaps the elevation could be computed from the drainage network analysis (length, parent/children number, density etc).
Well, very similar the classic geography exercise were you mark drainage basins . Probably GIS software might be able to extrapolate something from the network contours and "water" divides. -------------------- _______________________

Now that is dangerously believable (or would be with the vertical scale significantly reduced).

You (and Bjorn) are definitely onto something here, Mike. Understanding topographical relationships seems fundamental to understanding Titanian surface processes, perhaps even constraining surface properties & composition. Really interesting work!

Now with color added. (My attempt at recolorizing from Bjorn's rendering - not everything matches yet...):

Mãezinha!!!
I love the path you guys are following here! And then Doug arrives with a flyover of the whole scene...

A little something like this?

Totally WOW!!!!
