Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Rayner Glacier is a prominent glacier, 19 kilometres (10 nmi) wide, flowing north to the coast of Enderby Land just west of Condon Hills. It was sighted in October 1956 by Squadron Leader D. Leckie during a flight in an ANARE Beaver aircraft, and named by ANCA for J.M. Rayner, Director of the Bureau of Mineral Resources in the Australian Department of National Development.

Enderby Land geographical object

Enderby Land is a projecting land mass of Antarctica. Its shore extends from Shinnan Glacier at about 67°55′S44°38′E to William Scoresby Bay at 67°24′S59°34′E, approximately ​124 of the earth's longitude. It was first documented in western and eastern literature in February 1831 by John Biscoe aboard the whaling brig Tula, and named after the Enderby Brothers of London, the ship's owners who encouraged their captains to combine exploration with sealing.

Hansen Mountains is a large group of nunataks rising to about 300 m (980 ft) above the Antarctic plateau. The mountains are approximately 89 km (55 mi) south of Stefansson Bay and they extend 40 km (25 mi) from northwest to southeast in Kemp Land, East Antarctica. The Hansen Mountains were first mapped by Norwegian cartographers from air photos taken by the 1936–1937 Lars Christensen Expedition. They were named for H.E. Hansen, the Norwegian cartographer who compiled the maps for this and other Norwegian Antarctic expeditions.

Breitfuss Glacier glacier in Antarctica

Breitfuss Glacier is a glacier 10 nautical miles (19 km) long, which flows southeast from Avery Plateau into Mill Inlet to the west of Cape Chavanne, on the east coast of Graham Land. It was charted by the Falkland Islands Dependencies Survey (FIDS) and photographed from the air by the Ronne Antarctic Research Expedition in 1947. It was named by the FIDS for Leonid Breitfuss, a German polar explorer, historian, and author of many polar bibliographies.

The Central Masson Range is the central segment of the three parts of the Masson Range, Antarctica. It rises to 1,120 metres (3,670 ft) and extends 4 nautical miles (7 km) in a north-south direction. The Masson Range was discovered and named by the British Australian New Zealand Antarctic Research Expedition, 1929–31, under Douglas Mawson. This central range was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, and named "Mekammen". The approved name, suggested by the Antarctic Names Committee of Australia in 1960, more clearly identifies the feature as a part of Masson Range.
