Geodetic latitude is measured relative to the local horizon, while geocentric latitude is measured relative to the Earth's true polar axis. Geodetic latitude is the angle between the equatorial plane and the normal to the spheroid at that point, while geocentric latitude is the angle between the equatorial plane and a line connecting the point to the Earth's center. Geodetic latitude is measured in statute miles from the equator, while geocentric latitude is measured in nautical miles from the prime meridian. Geodetic latitude accounts for the Earth's rotation speed, while geocentric latitude is a static coordinate based on Keplerian orbits.
