Elevation. The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth 's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum ). The term elevation is mainly used when referring to points on the Earth's ...
This is a list of countries and territories by their average elevation above sea level based on the data published by Central Intelligence Agency, [1] unless another source is cited. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1.
Kingman Reef high point – less than 7 feet (2 m) [92] Midway Atoll, Sand Island high point – 50 feet (15 m) [92] – The highest point of the U.S. minor outlying islands in the Pacific Ocean. Navassa Island high point – 280 feet (85 m) [91] – The highest point of all the U.S. minor outlying islands.
Height above mean sea level. Height above mean sea level is a measure of a location's vertical distance ( height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level. In geodesy, it is formalized as orthometric height. The zero level varies in different countries due to different reference points and ...
Mount Washington, is an ultra-prominent mountain in the state of New Hampshire. It is the highest peak in the Northeastern United States at 6,288.2 ft (1,916.6 m) and the most topographically prominent mountain east of the Mississippi River . The mountain is notorious for its erratic weather.
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large- scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods. Traditional definitions require a topographic map to show both ...
Mount Whitney (Paiute: Tumanguya; Too-man-i-goo-yah) is the highest mountain in the contiguous United States, with an elevation of 14,505 feet (4,421 m). [1] It is in East–Central California, in the Sierra Nevada, on the boundary between California's Inyo and Tulare counties, and 84.6 miles (136.2 km) [8] west-northwest of North America's lowest topographic point, Badwater Basin in Death ...
