I decided to draw an entire hemisphere in Fractal Terrains, label it, upload.

Map directions for the Northern Hemisphere. North at the top, south at the bottom, east to the right, west to the left.

And do detail maps as I have time. Size is 25000 by 12500 miles.

edit: New map, Oct 16, 1600 × 800 pixels

I have renamed one of the Barrow Islands.

Ocean currents: gold/yellow color warm current (surface); light blue color cold current (ocean depths); medium blue color cool current ( mid level).
