geodetic longitude

geodetic longitude

[¦jē·ə¦ded·ik ′lān·jə·tüd]
(geodesy)
The angle between the plane of the reference meridian and the plane through the polar axis and the normal to the spheroid; a geodetic longitude differs from the corresponding astronomical longitude by the amount of the prime-vertical component of station error divided by the cosine of the latitude. Also known as geographic longitude.

geodetic longitude

The angle between the plane of the reference meridian and the plane through the polar axis and the normal to the spheroid. It is the astronomical longitude corrected for the prime vertical component of the deflection of the vertical divided by the cosine of the latitude. This is the longitude used for charts. Also called geographic longitude

The origin of the coordinates coincides with the ellipsoidal centre of the geodetic coordinates (Fig), planes XOY, XOZ and YOZ coincide with the planes of the ellipsoidal equator, geodetic prime meridian (L = [0.sup.[omicron]]), and geodetic longitude (L = [90.sup.[omicron]]).
