MERCATOR VS. GALL-PETERS

• Mercator Map Projection: Invented by Flemish cartographer Gerardus Mercator for ships navigating across the Atlantic Ocean in 1569. The map is meant for direction. However, the projection distorts sizes of areas, especially closer to the North and South poles

• Gall-Peters Map Projection: Introduced in 1974 by Arno Peters and James Gall, and focuses on keeping landmasses equal in area. As a result, the shapes are distorted, and the map looks unfamiliar to viewers
