Background on Hobo-Dyer Map
This new map belongs to the family of Cylindrical Equal
Area projections in which the latitude and longitude lines
form a rectangular grid. Other projections in this family
include the Lambert, Gall, Behrmann, Edwards and Peters. The
HDP retains qualities of the other equal area cylindrical
projections, but is more visually satisfying.
Commissioned by ODT, Inc., created by British
cartographer, Mick Dyer, the map was derived by modifying
the 1910 Behrmann projection. Behrmann placed the standard
parallels at 30° north and south. On the HDP map, the
"cylinder" is assumed to wrap round the globe and cut
through it at 37½° north and south. In order to preserve the
equal area property the shapes of the landmasses become
progressively flattened towards the poles, but shapes
between 45° north and south are well preserved.
Due to the unusual proportions of the new map, ODT also
printed eight other map projections for comparison purposes
on the border of the map. The reverse side of the HDP map
shows the exact same projection, but with two somewhat
startling changes: south is on top and Australia is shown in
the middle of the map. How does such a simple thing as
reversing the poles or changing the "centering" influence
your impression of what's important? |
