I'm a bit scattered I'm afraid, but I really want to redo my old map of Mars for my Elzevir world. I'm going with a very huge base from USGS for this, in order to work out the details...
Just testing right now, so every comment is welcome!

This is approximately a quarter of the map (without the poles), and sadly, I already had to split it in two...
