Maps and How We Use Them
Historical Maps

East Oriented at Top
Francesco Rosselli’s Map 1508
Leonardo da Vinci 1514

World Political Map: April 2001
Types of Maps:
Comparing Projections
Mercator Map
Mercator: Good for: Navigation, shapes correct for small areas
Bad for: cannot represent poles; sizes are exaggerated the closer you get to poles
Looks like: rectangle
Purpose and Date: 1569; made to help sailors navigate
Significance: NEVER meant to be used as “THE” world map -- but it is!
Mollweide Map
Mollweide:
Good for: pleasing appearance; sizes and shapes in middle ok
Bad for: polar regions compressed
Looks like: ellipse
Date: Presented by Carl B. Mollweide (1774-1825) of Germany in 1805.
Significance:used to make homosoline and other maps
Buckminster Fuller's Dymaxion World Map
Fuller's Dymaxion World Map
Good for: minimizes distortion of size and shape
Bad for: directions and spatial relationships odd and obscure
Looks like: ??
Purpose and Date: 1980+, to represent shapes accurately
Significance: made to help us recognize “we’re all astronauts aboard a little spaceship called earth”
Goode’s Homolosine Map
Goode’s Homosoline
Good for: shapes (except Asia) are well represented
Bad for: map & oceans are interrupted
Looks like: ??
Purpose and Date: 1923; to represent shapes correctly
Significance:easy to reposition and re-center
Peter’s Map
Peter’s Map
Good for: relative sizes of land accurate
Bad for: water sizes not accurate; shapes are distorted; no poles
Looks like: rectangle
Purpose and Date:1974; to correct previous apparent sizes of land masses
Significance: shows continents to true sizes -- Africa MUCH larger than Europe!
Robinson’s Map
Robinson
Good for: shapes fairly well done
Bad for: areas away from equator exaggerated; poles are lines
Looks like: oval, except poles are lines
Purpose and Date: 1963; Canada and USSR much more correct than previous maps
Significance: used as National Geographic map for decades
Azimuthal Equidistant
Azimuthal Equidistant
Good for: to know distances from center of map; shapes in center well-represented
Bad for: farther from the center, shapes very distorted; can be hard to orient
Looks like: circle
Purpose and Date: 1426? Earlier? To display true scale and direction through center
Significance: can be recentered for anywhere on earth
Equidistant Conic
Werner: Heart Shaped
Sinusoidal
Van der Grinten I
Cassini
MacArthur’s Corrective
McArthur's Universal Corrective Map of the World
At last, the first move has been made - the first step in the long overdue crusade to elevate our glorious but neglected nation from the gloomy depths of anonymity in the world power struggle to its rightful position -- towering over its northern neighbours, reigning splendidly at the helm of the universe.
Never again to suffer the perpetual onslaught of "downunder" jokes -- implications from Northern nations that the height of a country's prestige is determined by its equivalent spatial location on a conventional map of the world.
This map, a subtle but definite first step, corrects the situation. No longer will the South wallow in a pit of insignificance, carrying the North on its shoulders for little or no recognition of her efforts.
Finally, South emerges on top. Spread the word. Spread the map! South is superior. South dominates!
Long live AUSTRALIA -- RULER OF THE UNIVERSE!!
