What is the significance of linear parameters in ellipsoid geometry?

• They determine the location of the Earth's poles

• They describe the angle of inclination of the Earth's axis

• They influence the atmospheric conditions on the Earth's surface

• They define the overall size and shape of the ellipsoid

Which type of latitude is the angle between the equatorial plane and a radial line connecting the center of the ellipsoid to a point on the earth’s surface?

• Geographic latitude

• Geodetic latitude
  

• Geocentric latitude

• Magnetic latitude

What is the purpose of using best-fitting ellipsoid models?

• To create simplified representations of the Earth for educational purposes

• To accurately depict the Earth's shape for geodetic calculations

• To determine the exact location of the Earth's geographic coordinates

• To study the variations in climate patterns across different regions
