How Does Spheroids, Ellipsoid, and Geoid - GIS Fundamentals and Mapping (4) Work?

Imagine Earth is like a squishy ball that isn’t perfectly round, it’s more like a slightly flattened sphere. That’s what spheroids, ellipsoids, and the geoid are all about, helping us map our world accurately.

A spheroid is like Earth if it were squished a little at the top and bottom, kind of like a slightly flattened orange. It’s still mostly round but not perfectly so. This helps when drawing maps that aren’t too far off from real life.

An ellipsoid is even more squishy than a spheroid, with different amounts of flattening depending on where you are, like how Earth’s shape changes slightly as you move around the globe. Think of it like a stretched-out rubber ball that's been squeezed from both sides.

The geoid is like Earth's true shape if it were covered in water, showing all its bumps and dips, kind of like how your bed looks after you've jumped on it multiple times. It helps create super accurate maps, especially when measuring height or depth.

These shapes help us understand and map our world better than just thinking of Earth as a simple ball.
