Then do Layer to “New Layer”(this keeps the land aligned – do this on both images): Then select your Mongesen layer and copy then paste. Basically you want to select the empty pixels as by default these are all land mass (well most of them). Then use the select by colour tool on your ocean only layer but select in the empty space. Next Lets get some variety into our land masses,Firstly on the ocean layer on both images trigger layer>Image size. But red and purple are achievable: Play around with a mix of colouize and layer modes for even stranger effects. Play around with different Gimp settings to get different ocean colours, I kept mine in a Blue/green pallette. Then do Layer to “New Layer”(this keeps the ocean aligned – do this on both images): Instant Deep Blue Oceans Copy the Ocean from the Mongesen layer and then paste. Use the select by colour tool in addition mode (2 red squares) to select all the shades of blue (I set my threshold to 20 but the default of 15 works fine). However you probably don’t want all your blue/green planets the same exact colour.
You can leave it there and jump down to adding clouds below. Then right click on your Mongesen layer and select “ New from Visible“: Set the Mongesen layers on both images in Gimp to Layer Mode “Overlay”. Then set the Map palette to “Mogensen” and copy/paste the new globe onto your globe Image in Gimp as a new layer and likewise with your map image: (Note: if you right click save as and then open these in GIMP ensure you change the image mode to RGB) Set the Map palette to “Atlas” and right click and copy the globe image and the flat map Images into Gimp as separate “New Images”. I’ve found a flat map image height of 1000px works well Most importantly once you settle on a globe record all the settings this will let you recreate the same globe at a later date.

Go to donjohn’s fractal world generator and generate a random world, make sure you check the resulting flat map (press create) before settling on a final globe and play around with rotation angle to get a nice view. Making a Blue Green Earth type planet – XCF Demo File Here

If you really just want something to use in a hurry feel free to grab one of these. I’ll only cover one planetary type today – a Blue/Green earth type globe. I am by no means a GIMP expert so I’m sure there are other (better) ways of producing the below effects but hopefully it’ll get you started. Naturally to follow the below your going to need a copy of GIMP installed and probably this Script pack which I use heavily. This doesn’t make beautifully photo realistic planets but it makes passable globes for use on a solar system overview images/maps and provides you with a matching world map you can take and work on later.
The reason I use the fractal world generator is it generates a nice globe and a flat map projection in several variates and gives a nice working base to whip some planets up in Gimp. The below process makes heavy use of donjohn’s fractal world generator, I’m unsure what copyright the images it generates are under but for personal use you should be fairly right. In my previous solar system post I covered some basics around making a Solar system so hopefully this post will help flesh out the solar system a little more. I’ve been helping a friend out making some planets, now he needs lots so I had to develop a technique for making planets quickly in Gimp.
