Map Projections - II

Have you ever thought about how to draw a map of a round planet like Earth without wrapping the paper around it? One way is to place flat paper directly over a specific point.

This is the idea behind the Gnomonic projection, where the paper touches Earth at just one point. Shapes and sizes near this point are accurate, making it perfect for mapping small areas, like the poles.

For a more balanced view of the entire world, there’s the Robinson projection.

This projection uses mathematical formulas to make landmasses appear closer to their actual shapes and sizes. Its oval shape avoids the heavy distortions seen in rectangular maps.

The Robinson map is most accurate within 45° of the equator, where shapes and distances are more precise.

In 1988, the National Geographic Society adopted the Robinson projection for its world maps because it offered a more accurate and visually pleasing representation of Earth.
