Let's assume you have a high resolution starting image which has pixel dimensions say 3600 pixels wide and 1800 pixels high. Unfortunately it's useful only for bitmap images. Its filter Deformations > Cartesian Transform converts easily a rectangular slice of your map to the wanted form. Krita, GIMP, Photoshop and Paint.NET have all freeware plugin named G'MIC effect collection. My suggestion belongs to the same class - to plugins. Someone has quite recently added a bunch of 3rd party software suggestions. Now you want to remap the equirectangular planar map to Gauss-Kruger style (still planar) slices.Īs others have said years ago, common graphic programs do not have the the wanted transformation as one click effect. The starting image you showed is an equirectangular earth map - a planar projection which is exact on the equator and stretches toward the poles to present spherical meridian-parallel rectangles as equally sized planar rectangles. How to get those slices - that was the problem in the question. Sorry for disturbing you beforehand with future difficulties. Unfortunately I do not know enough of it for any useful details. If the map paper happens to have somehow non-uniformly directed fibers the case can be complex. The right squeezing percentage surely depends on the used materials, too.

His gluing workflow stretches them just the right amount to fit. The globemaker in the video says that he uses map slices which are printed a couple of percents too small. Mathematicians say that no planar slices will bend exactly along a sphere, some squeezing or stretching is a must. In the next video a globemaker reveals some details of his process.

Making an actual globe map needs a substantial amount of handcrafting experience.

A lot of water has flown through the Strait of Messina since the question was new, but nothing worth of your acceptance has still appeared.
