Mercator vs.

The Mercator Myth

The Mercator projection, a ubiquitous feature of world maps, is renowned for its navigational utility, particularly in marine navigation. Its failed equivalence between size and distance is like an optical illusion that fools the eye. Initially created in 1569, the Mercator map presents continents and landmasses as significantly larger or smaller, directly affecting one's perception of the world. The Mercator map inflates the size of areas close to the poles, while condensing those near the equator."Greenland appears larger than Africa" on a Mercator map. But, in reality, Africa is roughly fourteen times the size of Greenland. The distortion is so pronounced that Europe is depicted as roughly equal in size to South America, despite the latter being nearly twice as large in reality. This distortion results in a skewed global perspective, with countries near the equator often underestimated in significance and size. The Mercator projection is constructed using cylindrical map projections, which can mislead viewers by stretching areas at the poles. Polar regions are magnified, which disproportionately enlarges landmasses such as Greenland. This global distortion has long been a critical flaw, even though it is practically useful for navigation. Seeing Greenland as a massive landmass on these maps makes Greenland seem like a nearly continent-sized mass, similar to Africa, rather than a much smaller island.

The Equal Earth Projection

The Equal Earth projection provides a more expansive, accurate map of our world. It emphasizes accurate proportions, ensuring the relative sizes of landmasses are depicted accurately without the exaggerated polar distortion as seen in the Mercator projection. In this map, Africa is accurately shown as a large landmass. Greece, Italy, Alaska, and the Caucasus are positioned on the margins of the map, and the maps are color-coded to indicate political boundaries. The Equal Earth projection is designed to balance accuracy and balance by presenting all geometric parameters and scales more accurately. Instead of the traditional Mercator projection's true shape, the Equal Earth projection is constructed as a pseudo-cylindrical map projection, a map that better preserves the integrity of geographical areas and distances. It corrects for the misleading overstretch of polar regions. The Equal Earth projection aims to offer an uncompromised portrayal of the true size of Africa. It emphasizes the true size of Antarctica. It correctly scales down the size of polar regions, giving a more balanced view of the Earth. The Equal Earth projection was designed to provide a more accurate representation of the continents' actual sizes in relation to each other. Unlike the Mercator projection, which distorts the size of landmasses, the Equal Earth projection portrays Africa as more than 4 times the size of Greenland. In a compelling demonstration of accurate proportions, the Equal Earth projection emphasizes the true scale of the world, making it an essential tool for educators and mapmakers.

Maps and Perception

The Mercator projection’s influence extends far beyond navigation. Today’s most up-to-date displayed maps are still based on the Mercator projection, a colonial hangover that has influenced modern perceptions of global geography, still creating a perception of the Earth as an over-sized landmass. In the contemporary world, where world maps are commonly found in classrooms, textbooks, and digital media, many people rely on Mercator maps to understand the world. But this widespread misrepresentation can distort our understanding of global geography, politics, and culture. Many maps today still use the famous Mercator projection, inadvertently reinforcing colonialist narratives about geographic distances and sizes. As the Equal Earth projection indicates, our perception of the world is shaped and distorts by how we map it. Thus, the maps we choose to use can have a profound impact on our understanding of the world, emphasizing the importance of accurate map projections for a true representation of the world.

The Nonbinding Resolution and Its Repercussions

If a map accurately reflects the true relative sizes of landmasses, it is likely to be perceived as less accurate by surveyors or mapmakers. The question of using alternative map projections such as the Equal Earth projection raises the question of practical benefits. While the Equal Earth projection offers a more accurate representation of the world, it is not widely adopted as it is not binding. The maps will not change overnight. But a move away from the Mercator projection could mean a shift in how we perceive the world. The Equal Earth projection might be seen by the public as helpful, making it easier to think about geography and cartography. Exploring alternative map projections such as the Equal Earth has become necessary to consider whether it is accurate and useful.
