The geoid
The animation is based on available gravity measurements and shows the information GOCE will be providing us with. Simplified, it shows how the geoid represents deviations from the Earth's elipsoid. Although it has 'highs'and 'lows'- it is a surface of equal gravitational potential. Therefore, if an object were placed on the surface it would ...

📌 Ellipsoid vs Geoid — Easy Explanation for Surveyors Understanding the difference between Ellipsoid and Geoid is very important in land surveying, GPS work, and elevation calculations. 🔹 Ellipsoid A smooth, mathematical model of the Earth used in: GPS calculations Mapping & coordinate systems Lat, Lon & Ellipsoidal Height (h) Example: WGS84 🔹 Geoid A natural gravity-based shape of the Earth that represents Mean Sea Level (MSL). Used for: Orthometric Height (H) Elevations above sea level Exam
