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.

Mount Keyser is a mountain 3 nautical miles (6 km) east of Mount Ryder, in the eastern part of the Tula Mountains in Enderby Land, Antarctica. It was plotted from air photos taken from Australian National Antarctic Research Expeditions aircraft in 1957, and was named by the Antarctic Names Committee of Australia for D.O. Keyser, a radio officer at Mawson Station in 1961.

Tula Mountains

The Tula Mountains are a group of extensive mountains lying immediately eastward of Amundsen Bay in Enderby Land, Antarctica. They were discovered on January 14, 1930 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Mawson and named "Tula Range" by him after John Biscoe's brig, the Tula, from which Biscoe discovered Enderby Land in 1831. The term "mountains" was recommended for the group following an ANARE sledge survey in 1958 by G.A. Knuckey.

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.
