How do I go about creating a map of the earth in QGIS or Openstreetmap, etc. and then export art in the appropriate projection so that it can be wrapped around a sphere?

So you want something you could print?– BradHardsMay 16, 2017 at 23:45

Yes. Something that we can print to manufacture globes– milesmeowMay 16, 2017 at 23:46

In general, you can't do this exactly- a flat object can't match a sphere. You can make something that will be close by taking small sections, but how large your sphere is, and how close it needs to be determines the layout. Its an interesting question - I don't know of anything in QGIS that does this.– BradHardsMay 16, 2017 at 23:49

Is there a tool that can transform a 2D map to various projections? Seems like an image manipulation tool that potentially exists.– milesmeowMay 16, 2017 at 23:58

Maybe we don't have common understanding on "various projections". The concept is normally about how the 2D view of a 3D object is presented.– BradHardsMay 17, 2017 at 0:04

Using QGIS Only
Follow the instructions at: Projecting a world map on 6 segments to print on ball
In brief, use the 'Sphere_Polyconic, EPSG:53021' projection and produce multiple 'gores', separately, and then join them together. ('Gores' are the curved wedge shapes that you can cut out, bend and join to form a sphere).
Warning: This is NON-TRIVIAL!
Using Commercial Software:
If you have Photoshop, this is MUCH easier...
You could use the Photoshop 'Flexify' plugin to automatically produce all the 'gores' already joined at the equator. You can get it from here:

For an good example of what it can do, search for "gores" at:
