Description

The final version was described by Buckminster Fuller in 1954. For more information, refer to the Buckminster Fuller Institute Website at www.bfi.org.

Illustration of the Fuller projection

Projection method

This projection converts the globe into a 20-sided figure called an icosahedron. Each side is a geodesic triangle that is then flattened into a two-dimensional triangle. The facets of the icosahedron are unfolded in a specific manner to keep the land masses unbroken.

Lines of contact

The tangent lines are the facet edges.

Linear graticules

In general, neither latitude nor longitude lines are straight.

Properties

Shape

Distortion increases as the distance from the facet edges increases. Because the Fuller projection is comprised of 20 facets that are projected individually, overall shape distortion is low.

Area

Distortion increases as the distance from the facet edges increases.

Direction

Generally directions are distorted, depending on the orientation of a facet. Angles within a facet are slightly distorted due to the flattening of the geodesic triangle.

Distance

The scale is correct along the facet edges.

Limitations

The north direction is not upright. It is difficult to identify directions without a graticule on the map.

Uses and applications

Best used for display and educational uses.

Parameters

Desktop

  • False Easting
  • False Northing
  • Option
Note:

Using zero (0) for the Option parameter will display the entire Fuller projection. If you use 1 through 20, a facet corresponding to the given value is displayed.
