Which is the best map projection?


The ‘orange peel problem’ is perhaps the most widely-cited analogy that geographers use to explain why a three-dimensional world cannot be represented in two dimensions sans any kind of distortion. Try as you might, you just cannot flatten an orange peel without tearing, squashing or stretching it. Likewise, when cartographers try to flatten the Earth for a map projection, distortions in terms of shape, distance, direction, or land area are inevitable to creep in.

Depending on the purpose they are trying to serve, the number of possible map projections is limitless. However, which map projection should be used for general purposes, such as, for hanging in classrooms or on TV news? Here’s how some popular projections weigh against each other:


The most popular map projection in the world has been around for 448 years now. It was created by Flemish cartographer Gerardus Mercator in 1569 – a time when Antarctica hadn’t even been discovered. Mercator was designed as a navigational tool for sailors as it was most convenient to hand-plot courses with parallel rules and triangles on this map.

In most maps, when you try to fix one kind of distortion, you increase another kind of distortion. However, Mercator is one of those rare maps whose answer to latitudinal distortion was to ensure that the longitudinal distortion is equally bad!

On a Mercator projection, Greenland is roughly the same size as Africa. In reality, Africa is almost 14 times larger, and Greenland can fit inside China no less than four times. The map also suggests that Scandinavian countries are larger than India, whereas, India is actually three times the size. And yet, Google Maps, Bing, Yahoo and even OpenStreetMaps continue using some version or the other of the Mercator to display the world.

Pros: Sailors loved it; preserves angles and directions in a small area

Cons: Bad for understanding the real size and shape of continents and countries

The biggest criticism for the skewed Mercator projection came in 1973 from German filmmaker and journalist Arno Peters. Peters argued that by enlarging Europe and North America, Mercator maps were giving white nations a sense of supremacy over non-white nations.

His solution? An equal-area projection that would show the correct sizes of countries relative to each other. Not that the Gall-Peters projection came without any flaws. In its quest of removing size distortions, the map stretched some places near the poles horizontally to a shocking degree. It also stretched land masses vertically near the Equator. So, if the map looks really odd to you, it’s because the shapes and angles are all wrong – exactly the reason why we don’t see this map online much. Nevertheless, it’s quite widely used in the British school system.

Pros: The only ‘area-correct’ map of its time; got featured in The West Wing (S2E16)

Cons: Galled the cartographic community in the 1980s

American geographer and cartographer Arthur H. Robinson came up with this projection in 1963, focusing more on the ‘look’ of the map than precise measurement of places. Robinson intended the map, which is neither equal-area nor conformal, as a general purpose tool.

In fact, he told the New York Times in a 1988 interview, “I decided to go about it backwards. I started with a kind of artistic approach. I visualized the best-looking shapes and sizes. I worked with the variables until it got to the point where, if I changed one of them, it didn’t get any better. Then I figured out the mathematical formula to produce that effect. Most mapmakers start with the mathematics.”

Hopefully, this map would replace Mercator in classrooms.

Pros: Shows the entire world at once

Cons: Compromises both area and angles, especially at the poles

Proposed by German cartographer Oswald Winkel in 1921, the Winkel-Tripel projection is quite the opposite of Robinson. The map resorts to mathematics to curtail three major types of distortion – area, direction, and distance (and hence the German term for ‘triple’, Tripel, is in the name). This map projection shows Greenland as the same size as Argentina, and not as the size of all of South America.

The National Geographic Society has been drawing all its standard maps using the Winkel-Tripel projection since 1998, and many US schools have followed suit. However, despite its popularity, since the map doesn’t preserve angles, it is nowhere close to replacing Mercator for navigation purposes.

Pros: Reasonably accurate shapes and sizes of countries

Cons: Land masses closer to the poles still enlarged

This is hands-down the most accurate map projection in existence. In fact, AuthaGraph World Map is so proportionally perfect, it magically folds it into a three-dimensional globe.

Japanese architect Hajime Narukawa invented this projection in 1999 by equally dividing a spherical surface into 96 triangles. These triangles were then projected onto a tetrahedron, which not only helped maintain the proportions of land and water, but also helped to unfold the map into a perfect, flat rectangle. Narukawa, however, insists that if the map is refined a step further to increase the number of subdivisions, its accuracy will improve and it can officially be called an area-equal map.

Nonetheless, AuthaGraph realistically represents all oceans and continents, including the neglected Antarctica. And while the general shape of the continents is maintained, you will notice that their orientation is skewing upwards – as if in a smile!

Pros: Most accurate; will win you Japan’s biggest design award; can be folded into a 3D globe

Cons: The Arctic Circle gets somewhat squashed

  1. `AuthaGraph: This is hands-down the most accurate map projection in existence`

    This is just popular bollocks. AuthaGraph doesn’t preserve angular details as well as the Dymaxion that inspired it – e.g. squashed Brazil and lop-sided Australia.

  2. “The only area-correct map of its time”? Lambert cylindrical projection has existed since the 1700s! Gall–Peters is just one of the many vertically stretched variations. Also sinusoidal, Albers, Mollweide, Bonne, etc predate Gall–Peters and are equal-area as well.

  3. Winkel Tripel’s Africa is very unrealistically skinny. That’s a funny thing to find in a compromise map. Some equal-area maps distort Africa (and other tropical places), but there’s no excuse for that in a map with no properties.

    For example, compare Winkel to Ecert III, another line-pole compromise map.

    Winkel has terrible NS/EW scale-disproportion up to lat 30. And the +30 to -30 latitude band encompasses half of the Earth’s surface. In fact, look at Winkel’s U.S. It, too, is severely east-west compressed. It’s ridiculous to find that in a non-equal-area map. The +49 to -49 latitude band encompasses 3/4 of the Earth’s surface.

    There’s no excuse for that ridiculous amount of extreme distortion in a map that isn’t equal-area.

    Robinson’s projection was designed to look good, and it does. Also, Robinson designed his map to not greatly magnify the Arctic. Yes, Robinson flattens the Arctic a lot, but Robinson must have felt, and I agree, that a more accurate size for the Arctic is more important than accurate shapes for regions there. Winkel uses extreme horizontal compression to reduce that flattening, thereby making the Arctic more unrealistically large, and making the entire rest of the world too east-west compressed.

    You said that Winkel scored best in a ratings-study that measured distortions. Yes, and that’s because that study aggregated by root-mean-square. RMS preferentially fixes the biggest errors. With a flat pole, the Arctic ordinarily has the biggest errors. So, being more sensitive Arctic flattening, the rating-program favored the Arctic, and gave top rating to a map that east-west squashes the rest of the Earth to improve shapes in the Arctic.
