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 ...
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 (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 ...
Islands average only one to two square kilometers in area, and lie between 1–1.5 m (3 ft 3 in – 4 ft 11 in) above mean sea level. [1] Although some of the larger atolls are approximately 50 km (31 mi) long from north to south, and 30 km (19 mi) wide from east to west, no individual island is longer than eight kilometers. [5]
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).

Ulaanbaatar is located at about 1,350 metres (4,430 ft) above mean sea level, slightly east of the center of Mongolia, on the Tuul River, a sub-tributary of the Selenge, in a valley at the foot of the mountain Bogd Khan Uul. Bogd Khan Uul is a broad, heavily forested mountain rising 2,250 metres (7,380 ft) to the south of Ulaanbaatar.
It is 1,086 metres (3,563 ft) above sea level, and about 19 metres (62 ft) higher than the cable station at the western end of the plateau. The cliffs of the main plateau are split by Platteklip Gorge ("Flat Stone Gorge"), which provides an easy and direct ascent to the summit and was the route taken by António de Saldanha on the first ...
