I tried to clean up that awful purple river on the leaked map. There's actually a lot of hidden detail in there amongst all that blue and purple which is actually land.
I chucked my map in a 3D engine and created a displacement map, with tessellation. Looks kinda cool seeing it in 3D. It's not that accurate, but still nice to see the map in that way.
Take a look at it yourself in 3D if you want: https://skfb.ly/6AWL7
