Polyhedral Maps in Paper

Have Fun with Paper Models of the Earth

Assorted paper pseudoglobes
Some paper polyhedra you can build yourself

Polyhedral map projections are an interesting compromise solution to the problem of accurately representing curved features on flat surfaces while minimizing the distortion of cartographic properties. From here you can download, print, cut and build your own polyhedral pseudoglobe (if you have no experience building paper or card models, please read the assembly tips).

On Sizes and Resolution

I'd like to provide images in the highest possible resolution, but my server's disk space and bandwidth are constrained. In time, these limits have been enhanced, but still exist. Maps in this section can be:

"Low-resolution"
PNG files which may be printed directly from your browser
"High-resolution"
PDF files with somewhat better resolution; require Adobe® Reader® ("Acrobat Reader"), version 5.0 or more recent, or compatible software like Xpdf, version 3, or Evince, version 0.5.
"Resolution-3"
PDF files with at least 300dpi. I could call them "higher-resolution", but someday I will run out of words, so I'll use numbers from now on...

All PDF files are in A4 size; most PDF viewers allow adjusting printing size to letter, A3 or other dimensions.

World maps on a rhombic dodecahedron

Disclaimer
Although I have carefully programmed my mapping algorithms, I offer no warranty about the precision of these images. The data sets used may be outdated, especially those with country borders.
