Why the Earth is not a perfect sphere, but an ellipsoid instead
Geodesy is the scientific discipline dedicated to measuring the Earth's precise dimensions and shape. This video explores how engineers determine land boundaries and how pilots navigate across oceans, revealing the technical reality behind our planet's actual physical form.
Geodesy, or Geodetics Engineering, provides the framework for understanding the Earth's size and shape. Rather than a perfect sphere, the planet is more accurately described as an ellipsoid.
This science is essential for practical tasks, such as defining the exact borders between land parcels, states, and countries. It also enables airline pilots to maintain accurate headings while flying over featureless oceans.
