That is an awe-inspiring amount of work. I mainly want a map to serve as guidance in climate construction; do you think a substantially lower-resolution topographic map (like this) would work for that? If so, what actually determines how high things are? From the maps I've seen so far, it looks like "things are high near plate collision zones and get lower as you move further away from them" is a standard rule, but that's probably a gross oversimplification.
