R. Buckminster Fuller was truly a modern Renaissance Man. Bucky created many inventions and championed several ideas that have shaped the way we live. One of his creations is the Dymaxion map projection. The map projection is rather complex; the developable surface is an icosahedron. When the icosahedron is then sliced and flattened, it produces a world map that is visually intriguing. It is truly unlike any other map projection.
In Zachary’s post, he also mentions the Faumaxion web map, which is a Flash-based web map that reorients itself so that north is at the top for any of the triangular faces of the Dymaxion projection. Michal Migurski, a partner at Stamen Design, has the details on how he created the Dymaxion slippy map.
The downside to using a Dymaxion projection in your web map is that the support for the projection amongst the mapping APIs is minimal. You will need to do more of the heavy lifting in order to get this projection working properly in your web map. That’s also ignoring the fact that many people are not spatially aware and that this different projection will require your audience to orient themselves with the way the Earth has been projected. While Spherical Mercator is common and familiar, it does grossly exaggerate the areas closer to the poles, which in turn distorts your mapped data. Choropleth maps depicting a variable dependent on area, such as population density, are often misleading when mapped with a Mercator projection. The Dymaxion map is closer to an equal-area map than most, however the variable orientation towards North makes this projection a hard sell to a general audience.
Nonetheless, the Dymaxion map is an incredible map projection, from both a scientific and aesthetic point of view. The time spent by some very dedicated, intelligent people to get this working in interactive form speaks to the admiration of the projection and its creator. If only Bucky had lived long enough to see what wonders the Internet hath brought…
