Map Projections
Map projections are techniques used to represent the curved surface of the Earth on a flat map. Because the Earth is a sphere, translating its features onto a flat surface inevitably distorts some properties, such as shape, area, distance, or direction. Different projections, like Mercator or Robinson, prioritize different aspects to suit specific needs—like navigation or presenting global data. Understanding these projections helps us recognize the limitations of maps and how they can influence our perception of geographic information.

Map projections are methods used to represent the curved surface of the Earth on a flat map. Since the Earth is a three-dimensional sphere, translating its features onto a two-dimensional surface involves some distortion. Different projections prioritize various aspects, such as shape, area, distance, or direction. For example, the Mercator projection preserves angles but distorts size, making Greenland appear larger than it is. Meanwhile, the Robinson projection aims for a balanced view, minimizing distortion overall. Understanding these projections helps us recognize the limitations and benefits of different maps we encounter.
