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.

Hoffman Point is an ice-covered coastal headland at the south side of the mouth of Bertoglio Glacier, where the latter flows into the Ross Ice Shelf, Antarctica. It was mapped by the U.S. Geological Survey from tellurometer surveys and Navy air photos, 1959–63, and named by the Advisory Committee on Antarctic Names for Commander G.L. Hoffman, Civil Engineer Corps, U.S. Navy, commander of Mobile Construction Battalion Eight at McMurdo Station in U.S. Navy Operation Deep Freeze 1964. [1]

Bertoglio Glacier is a glacier 7 nautical miles (13 km) long, flowing from the Conway Range eastward between Cape Lankester and Hoffman Point to the Ross Ice Shelf. It was mapped by the United States Geological Survey from tellurometer surveys and Navy air photos, 1959–63, and named by the Advisory Committee on Antarctic Names for Commander Lloyd W. Bertoglio, U.S. Navy, commander of the McMurdo Station winter party, 1960.

Ross Ice Shelf ice shelf in Antarctica

The Ross Ice Shelf is the largest ice shelf of Antarctica. It is several hundred metres thick. The nearly vertical ice front to the open sea is more than 600 kilometres (370 mi) long, and between 15 and 50 metres high above the water surface. Ninety percent of the floating ice, however, is below the water surface.

The Advisory Committee on Antarctic Names is an advisory committee of the United States Board on Geographic Names responsible for recommending names for features in Antarctica. The United States does not recognise territorial boundaries within Antarctica, so ACAN will assign names to features anywhere within the continent, in consultation with other national nomenclatural bodies where appropriate.
