You know it occurs to me that some of the more modern map projections might be possible in PS and GIMP using some of the transforms... I may just give that a whirl at some point and if I succeed I'll create an action that can recreate the steps.
It just so happens that I may actually be able to provide that expression. It might take a couple days though.
EDIT: After looking at the expressions, it looks like you are constrained to the size of your image and the result must match. They may not work as I was thinking of doing an Iso map which would require slicing the image.
I just downloaded the Felimage plugin and it's very good. I've been struggling to get noise to do some things and this has sorted out a few problems really nicely.
I've attatched a forest pattern I made using Felimage in less than 2 minutes. It could quite easily be more effective and a better shade of green.
Cheers for that!
or am I missing something
You can also get a useful heightmap out of FT by going to "Map" -> "Show other Shader" -> "Show Bump map". Export that at a VERY large size, and use it for an image heightmap. This image is a result of importing such a height map into a Carrara terrain object, and placing the camera to a good looking area.
Anyway, for images mapped to spheres, I strictly use the 2:1 ratio. Of course, I map a lot of images to 3d objects, so you're milage will vary based on what the resulting image is for.
For those running 2.6 it seems a lot of those scripts weren't sent with the binaries... here's the one I found... http://registry.gimp.org/node/8172
edit grr: this one actually creates a space view of a planet... I'll keep looking...
In most cases any one that creates a new image has been moved to the File>Create menu instead of the old xtns menu.
This happened as a part of adding an empty image window on startup.

Thanks for the notice about the shuffling of options in GIMP 2.6.
