This is excellent - great work! The old one was good, but I have to admit that I didn't like looking at places like Russia where its sorta just blobs with only 2 or 3 height levels. This one looks much much much better.I had to manually align the map pretty much everywhere, this process was extremely painful and took many hours. I had to align every island, every tiny bit of coast, and more. Even after all of this it's still not aligned well, especially in the arctic and eastern asia. I tried as much as I could, but I'm tired of having to look at this map and just want it out, it's good enough and better than the best we had, no?
If you combine it with @Bob Hope's bathymetry and rivers, plus a little bit of aesthetics tweaking, I think it ends up looking really really nice.
