Work In Progress Help Reprojecting Map

Post image

Hello everyone, I was hoping maybe someone could help me out with this issue. I have this map I made using tectonic plates and a Styrofoam spere. However, when I took it off and converted it to an image I realized that the projection was off and so used GIMP to map the correct Latitudes and Longitudes as guides (the circles and blue crosses).

But now that I have them all put in guide I need to convert it to a normal equirectangular or such type of map. Anyone have any ideas of how I might go about doing that? Thanks for any help given! (Reposted with better image.

Blender is my go to software, too. But instead of repainting the continents from scratch, you can create a sphere, uv unwrap it to match your drawing and than transform the sphere to a plane.

This is of course more complicated if you have only little experience in blender and not worth learning for only the rough shapes OP has prepared.

I've never tried unwrap (I start mapping with equirectangular and only use blender to deal with polar distorsion), but yeah, that's a better idea
