Hi! I'm Steve Bowers, an editor at Orion's Arm and I'm an inveterate worldbuilder. Recently I've been working on adding planetary maps to the many worlds described at Orion's Arm, and I've come here for some tips. I really like the fractal coastline tutorial, for instance.

Here are some of the most recent maps I've made, mostly using Planetgen and Gimp, with some input from NASA Blue Marble imagery. The planets are displayed in Celestia when they are finished.

Chorus Map (for more details on this planet see Chorus )

Audubon Map (for more details on this planet see Audubon)

Wurm (for more details on this planet see Wurm)

Grignard (for more details on this planet see Grignard)

Nadia (for more details on this planet see Nadia)

As you can see I've been trying out different styles, and the results are quite diverse. Hopefully here I'll learn some of your methods.
