Lo sapete tutti l’inglese, no? Non mi fate tradurre il mex che ho postatto su un forum inglese… 
I’d like to build globes for earth and other planets.
I found out that turning a mercator projection into “gores” allows building a globe, but it has very low precision on poles.
I’d need this kind of foldable map:

I’d need a program able to take a generic merkator projection in input to give out such a “foldable map”.
This program from NASA does lots of projections, but not the one I need:

This GIMP plugin creates equatore-centred gores, which is NOT what I need:

Other “gores” plugins:
