Latitude is an angle (defined below) which ranges from 0Â° at the Equator to 90Â° (North or South) at the poles. Lines of constant latitude, or parallels, run east-west as circles parallel to the equator. Latitude is used together with longitude to specify the precise location of features on the surface of the Earth.he reduced or parametric latitude, Î², is defined by the radius drawn from the centre of the ellipsoid to that point Q on the surrounding sphere (of radius a) which is the projection parallel to the Earth's axis of a point P on the ellipsoid at latitude.
Latitude is angular distance measured north and south of the Equator. The Equator is 0 degrees. As you go north of the equator the Latitude increases all the way up to 90 degrees at the north pole. If you go south of the equator, the Latitude increases all the way up to 90 degrees at the south pole.
