The Genius of Mercator Projections

The video explores the Mercator projection, created by Gerardus Mercator, a Flemish cartographer born in 1512. Despite his humble beginnings, Mercator's education and travels led him to become a mapmaker. He developed the Mercator projection to aid navigation, making longitude and latitude lines straight for easier compass use. However, it distorts land masses far from the equator. Despite this, its unique properties make it invaluable for marine navigation.
