The Mercator map was designed in 1569 by the Flemish cartographer Gerardus Mercator to help European explorers navigate across the world.

The distortion of his map is a result of the fact that it is impossible to accurately represent the surface of a globe on a two-dimensional chart.

Whenever a map of the world is drawn, compromises need to be made.

The Mercator map shows the curvature of the Earth by making countries near the equator seem smaller than they are, with countries nearer the poles appearing bigger.

In an effort to correct this, a team of cartographers in 2018 created an equal area map they called the Equal Earth projection.

In February, the AU’s 54 member states adopted it, saying it “more accurately represents the sizes of all continents, particularly Africa”.

Ahead of Friday’s vote, Togolese Foreign Minister Robert Dussey told the Reuters news agency: “A fair world begins with a fair map.”

Earlier he had told a UN briefing: “A map is never neutral. It shapes perceptions, influences how the place of peoples and continents in the world is understood.”

The UN vote is non-binding but will see changes to the maps used by institutions around the world.
