Panels on Hobo-Dyer Map
on this innovative map are comparison panels. They include:
Buckminster Fuller's Dymaxion World Map (new satellite
composite version - 2002), The Eckert II projection,
Leonardo da Vinci's Mapamundi (from 1514, the first map of
its kind and one of the first world maps that used the name
"America"), Van Sant's GeoSphere (on a Robinson projection),
Guelke's Toronto-centered projection, the Oxford Globe,
Goode's Homolosine, and a Population Cartogram.
Below are the panels with explanations.
Dymaxion World Map
The visionary Fuller designed this map to help us
recognize that "we're all astronauts aboard a little
spaceship called Earth." This view of the Earth minimizes
the distortion of size and shape. Directions and spatial
relationships, however, tend to be obscured
The Eckert II Projection
One of a series of six projections developed by Max
Eckert (1868-1938). This is an equal-area map with poles and
central meridians at half the length of the equator. The
meridians are broken straight lines. Image courtesy of
Leonardo da Vinci's Mapamundi
This "octant" map is dated approximately 1514. The sphere
of the globe was divided into eight equilateral spherical
triangles, each section bounded by the equator and two
meridians 90% apart. This was the first map of its kind. It
is noteworthy for at least two other reasons: It was one of
the first world maps that used the name "America," and it
was one of the first world maps to lay down a south-polar
continent. Some critics believe the map was not really a
work by da Vinci himself, since the accuracy and mastery in
drawing are not reflective of his usual high standards. It
was more likely done by some trustworthy clerk or copyist
under da Vinci's employment.
Every map gives up some aspect of reality in order to
present another. On this map each country is shown
proportional to its population. The map gives up territory
to present people. You may not be able to make out the
little squares, but they are easy enough to see on the
original poster. Each square represents a million people.
Looking at the world this way is a revelation. From the
perspective of population, China is the biggest country in
the world! India is not far behind. For a real shock,
compare Indonesia with the United States. Compare Mexico
with Canada. Africa is not as big as the news sometimes
makes it. Asia has half the people in the world!
Van Sant's GeoSphere
The Van Sant GeoSphere image was the first cloud-free
satellite map of earth. It is presented here on a Robinson
projection. The GeoSphere map is the largest selling single
image of the world. It is used by numerous US federal
agencies and is licensed by photo libraries worldwide.

Guelke's Toronto-centered Projection
Leonard Guelke created this projection to tell you
exactly how far it was from anywhere on Earth to Toronto,
Ontario, Canada. Draw a straight line on this map from
Toronto to any location and, with some simple math, you've
got the real-world distance. In order to achieve this
benefit, you need to sacrifice some shapes and sizes.

The Oxford Globe image of the earth from space
Oxford Cartographers made the Oxford Globe in 1992 in
response to growing interest in world environmental issues.
It is a highly detailed relief model of the earth with
colors depicting vegetation and desert, compiled from a
two-year sequence of satellite imagery. This overcomes the
seasonal bias you see from snapshot satellite images which
can show dramatically different scenes from summer to
winter. Available (also with names and boundaries added)
from Oxford Cartographers.
On the Van Sant image the world appears smooth and whole. On
this image by John Paul Goode, the world seems cut into
sections. Which seems more realistic to you? The Van Sant
image we used is represented on a Robinson projection, while
the Goode Homolosine is an equal-area projection. Compare
the portrayal of shapes and sizes. What does the Van Sant
give up for the sense of continuity? What does the Goode
gain by giving up the sense of continuity?
