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, usually denoted symbolically by the Greek letter phi, \(\phi\,\!\), gives the location of a place on Earth north or south of the Equator. Latitude is an angular measurement in degrees (marked with Â°) ranging from 0Â° at the Equator to 90Â° at the poles (90Â° N for the North Pole or 90Â° S for the South Pole). The complementary angle of a latitude is called the colatitude.
