Thanks for the offer Jan. I will have to finish sketching on the globe, then I'll take the pictures and post them. (I'll post a very rough version, to get a feel for the technique, then I can redo the globe more nicely and tweak the importing/reprojecting part of the task at my leisure.) --Lloy

Hello - could anyone think of a way to accomplish this using hugin or any other software? I want to take a map that has been drawn on the surface of a painted-over globe, and create a flat image file that I could then reproject using other software (e.g. NASA G.Projector). My idea is that it sh
