I don't know if anyone around here is interested in experiments like this, but since most of the fundamental layer masks of this map have been painted by hand, I was wondering how it would look like with some real-world data.
So, just for fun, I stuffed some real-world data into most of the layer masks of the file. The remaining layers were set to invisible.
I don't know about the accuracy of the data... I just downloaded some files and threw them into the various layer masks I already had. Just to see how it would turn out.
Of course this map serves no purpose at all. It's born out of mere curiosity, nothing more.
Here is what I got:
