Height above mean sea level (AMSL) is the elevation (on the ground) or altitude (in the air) of an object, relative to a reference datum for mean sea level (MSL). It is also used in aviation, where some heights are recorded and reported with respect to mean sea level (contrast with flight level ), and in the atmospheric sciences , and in land ...
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.
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 historic measurement periods.
Aviation altitude is measured using either mean sea level (MSL) or local ground level (above ground level, or AGL) as the reference datum. Pressure altitude divided by 100 feet (30 m) is the flight level, and is used above the transition altitude (18,000 feet (5,500 m) in the US, but may be as low as 3,000 feet (910 m) in other jurisdictions ...
There are at least 108 mountains on Earth with elevations of 7,200 m (23,600 ft; 4.5 mi) or greater above sea level. Of these, 14 are more than 8,000 m (26,000 ft; 5.0 mi). [ 1 ] The vast majority of these mountains are located on the edge of the Indian Plate and Eurasian Plate in China , India , Nepal , and Pakistan .
Two-thousanders [1] are mountains that have a height of at least 2,000 metres above sea level, but less than 3,000 metres. The term is used in Alpine circles, especially in Europe (e.g. German: Zweitausender). The two photographs show two typical two-thousanders in the Alps that illustrate different types of mountain.
A view of Denver, the mile high city. The official elevation of City and County of Denver is precisely one mile (5,280 feet = 1,609.344 m) above sea level. When the United States National Geodetic Survey determined that Denver was actually 36.10 inches (917 mm) higher than previously thought, the city merely lowered its elevation reference point on the west steps of the Colorado State Capitol ...
Driskill Mountain (also referred to as Mount Driskill) is the highest natural summit in Louisiana, with an elevation of 535 feet (163 m) above sea level. [3] It lies about 5.3 miles (8.5 km) southeast of Bryceland, in Bienville Parish. A large pile of rocks marks the high point.
