The method
- Project the globe on a myriahedron
- Label the edges as cuts or folds
- Unfold the globe
A myriahedron is a polyhedron with a very large number of faces. For this reason, we call the results myriahedral projections. In step 2 and 3, this myriahedron is cut open and unfolded. The resulting maps have a large number of interrupts, but are (almost) conformal and conserve areas.
Examples
Now, dependent on which mesh is used and which strategy for labeling the edges, different maps are obtained. First, one can cut along parallels or meridians. We call these graticular projections, since they are based on the graticule. The resulting images resemble familiar map projections.
