What does a mercrater show?

A mercrater, or Mercator projection, is a cylindrical map projection that represents the Earth's surface. It maintains accurate angles, making it useful for navigation, but distorts size, especially near the poles, making landmasses appear larger than they are. This projection is particularly famous for its representation of equatorial regions while exaggerating the scale of areas such as Greenland and Antarctica. Overall, it provides a practical tool for sailors and navigators, despite its geographic distortions.
