Map Projections - I
Did you know Greenland can look gigantic on some maps and tiny on others? That's because no flat map can show the round Earth perfectly.
The Earth is a three-dimensional sphere, but maps are two-dimensional.
Mapmakers use projections to create a flat map, similar to flattening out an orange peel, but this process always causes some stretching or distortion.
Let's look at a few commonly used projections.
The Mercator projection projects Earth's curved surface onto a cylinder, accurately showing areas near the equator but distorting shapes and sizes near the poles.
Countries like Greenland appear much more prominent on the Mercator map than in reality because landmasses farther from the equator are stretched.
Another method is the conic projection, in which the Earth's surface is represented as if covered by a cone, making it more suitable for polar regions.
This projection is most accurate where the cone shape touches the globe along a specific line of latitude, usually the equator.
