Meaning and Definition
A cylindrical map projection that represents meridians as equally spaced vertical lines and parallels as horizontal lines spaced farther apart as their distance from the equator increases.
A specific method of projecting the Earth's spherical surface onto a flat map, which preserves angles and shapes of small areas but distorts size increasingly toward the poles. It is named after the Flemish cartographer Gerardus Mercator.

FAQ
Frequently Asked Questions
The Mercator projection stretches areas progressively as you move away from the equator. Greenland is far from the equator, so its size is greatly exaggerated compared to landmasses near the equator, like Africa.
Yes, it is still widely used for nautical navigation, web mapping services (like Google Maps for local scales), and in many educational contexts, though often alongside other projections for comparison.
Its main advantage is that it is conformal, meaning it preserves angles and shapes locally. This means a compass bearing appears as a straight line on the map, which is crucial for marine and aerial navigation.
It was developed by the Flemish cartographer and geographer Gerardus Mercator in 1569 for his world map 'Nova et Aucta Orbis Terrae Descriptio ad Usum Navigantium Emendata'.
