The United States Geological Survey defines sixty-two cartographic quadrangles for the surface of Venus, [54] with V-1 as the north pole region and V-62 as the south pole region. Base on the FMAPs, different groups of Venus researchers are mapping different quadrangles for the surface of Venus, resulting in different type of units defined.
The hemispheric view of Venus, as revealed by more than a decade of radar investigations culminating in the 1990-1994 Magellan mission, is centered on the North Pole. The Magellan spacecraft imaged more than 98% of Venus at a resolution of about 100 meters; the effective resolution of this image is about 3 km.

Note that Ishtar Terra is located near the negative pole if Venus's rotation is defined as prograde by the right-hand rule. [4] The rotation of the planet is commonly characterized as retrograde in order to correlate its northern hemisphere with Earth's, in which case Ishtar Terra is near the north pole. This is the convention normally used for ...
Longitudes on Venus are measured eastward from its prime meridian. The original prime meridian passed through the radar-bright spot at the center of the oval feature Eve, located south of Alpha Regio. [1] After the Venera missions were completed, the prime meridian was redefined to pass through the central peak in the crater Ariadne. [2] [3
The International Astronomical Union (IAU) defines the north pole of a planet or any of its satellites in the Solar System as the planetary pole that is in the same celestial hemisphere, relative to the invariable plane of the Solar System, as Earth's north pole. [1] This definition is independent of the object's direction of rotation about its ...
Chart of lunar maria with lines of longitude and latitude. The prime meridian is the centre of the near side of the Moon.. A planetary coordinate system (also referred to as planetographic, planetodetic, or planetocentric) [1] [2] is a generalization of the geographic, geodetic, and the geocentric coordinate systems for planets other than Earth.
