areography

(air-ee-og -ră-fee) The geography of Mars. Surface coordinates are defined by aerographic longitude and latitude. Longitude is measured in degrees westward from a prime meridian chosen to pass through the dark-albedo feature Sinus Meridiani near the Martian equator. The exact position of the meridian is now fixed by a 0.5 km crater pit, Airy–0, within the crater Airy, 300 km south of the equator.
