Out of Shape: How the Mercator Projection Has Led to Decades of Inaccurate Representations of Our World
For centuries, the Mercator projection has been the go-to map projection for navigators, cartographers, and the general public. Invented by Flemish cartographer Gerardus Mercator in 1569, this cylindrical projection has been used to represent the world in a convenient and easily understandable way. However, its widespread use has led to a myriad of inaccuracies and distortions that have been perpetuated for decades.
What’s Wrong with the Mercator Projection?
The Mercator projection has several flaws that have significant consequences for our understanding of the world. Here are a few examples:
- Inaccurate shapes: The projection distorts the shapes of countries, especially those near the poles. Countries like Greenland and Antarctica appear much larger than they actually are, while smaller countries near the equator, like Indonesia, are shrunk to tiny proportions.
- Misleading proportions: The Mercator projection exaggerates the size of features near the poles and shrinks those near the equator. This means that areas like Europe and North America appear larger than they actually are, while vast regions of the tropics appear much smaller.
- Tilted perspective: The cylindrical shape of the projection creates a tilted perspective that makes it difficult to accurately represent the world’s geography. This can lead to confusing representations of features like rivers, mountains, and coastlines.
The Consequences of Inaccurate Representations
The widespread use of the Mercator projection has had significant consequences for our understanding of the world. Here are a few examples:
- Geopolitical implications: The exaggerated size of countries near the poles can lead to a distorted view of their influence and power. This can perpetuate unfair stereotypes and biases.
- Environmental issues: The Mercator projection’s emphasis on polar regions can lead to a lack of attention to pressing environmental issues in the tropics, such as deforestation and climate change.
- Navigation and exploration: The inaccuracy of the Mercator projection can lead to navigational errors and delays, especially for sailors and explorers.
New Projections: The Future of Cartography
Fortunately, there are alternative projections that offer a more accurate representation of the world. Some examples include:
- The Gall-Peters projection: This projection attempts to preserve the shapes and sizes of countries more accurately than the Mercator projection.
- The Robinson projection: This projection uses a combination of cylindrical and azimuthal projections to create a more accurate and balanced representation of the world.
- The Winkel tripel projection: This projection uses a combination of projections to create a more accurate representation of the world, with a focus on preserving the shapes and sizes of countries.

FAQs
Q: Why is the Mercator projection still widely used?
A: The Mercator projection has been widely used for centuries and has become a standard in many fields. Its widespread use has made it a familiar and easily understandable representation of the world.
Q: Are there alternative projections that are more accurate?
A: Yes, there are several alternative projections that offer more accurate representations of the world. Some examples include the Gall-Peters projection, the Robinson projection, and the Winkel tripel projection.
Q: How can I get more accurate maps?
A: Many online mapping services, such as Google Maps and OpenStreetMap, offer alternative projections that are more accurate. You can also use specialized mapping software that allows you to choose different projections.
Q: What are the implications of using outdated projections?
A: Using outdated projections can lead to inaccurate representations of the world, which can have significant consequences for our understanding of geography, politics, and the environment.
