What is the difference between the geoid and the ellipsoid?
The geoid is the equipotential surface of the gravity field, while the ellipsoid is a mathematical model that approximates the shape of the Earth. The geoid is a mathematical model that approximates the shape of the Earth, while the ellipsoid is the surface that represents the three-dimensional surface of the Earth in the plane: latitude, longitude, and altitude. The geoid is the surface where the third dimension (z) corresponds to a certain theme, such as soil or population density, while the ellipsoid is the surface that represents any theme, such as topographic maps with terrain representation. The geoid is a mathematical model that approximates the shape of the Earth, while the ellipsoid is the equipotential surface of the gravity field.
A diferença entre o geóide e o elipsóide é que o geóide é a superfície equipotencial do campo gravitacional, enquanto o elipsóide é um modelo matemático que aproxima a forma da Terra. O geóide representa a forma real da Terra, enquanto o elipsóide é uma aproximação matemática da forma da Terra.
