View Full Version : How do I make a gore map

03-18-2012, 08:52 PM
I have a high-resolution topographic map of mars. I can't conceptualize it as a sphere and I need to draw some geographic regions on it. As such I was thinking of printing it out and making it into a globe then draw the regions on the globe, take it apart and scan it back in so I would have the regions I need flattened out appropriate to the actual globe.

As such, I need to know if there are any easy ways of making a gore map so I can do the globe. I found a gimp addon but I've never used gimp or would know how to use the addon.

Any help would be much appreciated, or if someone has a suggestion on how I could make this all easier that would be great too. See links below for more details:
