the level of the sea, which serves as the datum used for measurement of land elevations and ocean depths. Theoretically, one would expect sea level to be a fixed and permanent horizontal surface on the face of the earth, and as a starting approximation, this is true.

vertical distance of an object above some datum plane, such as mean sea level or a reference point on the earth's surface. It is usually measured by the reduction in atmospheric pressure with height, as shown on a barometer or altimeter.

The elevation of a feature is calculated through such surveying techniques as trigonometric triangulation and aerial photogrammetry. Elevation is represented by using contourscontour
or contour line,
line on a topographic map connecting points of equal elevation above or below mean sea level. It is thus a kind of isopleth, or line of equal quantity.

Elevation(religion, spiritualism, and occult)
Elevation is the angular distance of a celestial body above the horizon. An elevated planet in a natal chart, especially if it is near the midheaven and in the tenth house, is said to exert a particularly strong influence on the entire chart. In traditional astrology, elevated malefic planets, especially when elevated above the Sun and Moon, were said to exert an unfavorable influence over the entire chart. Modern astrologers have largely rejected this interpretation. For instance, a well-aspected Saturn (traditionally considered the Greater Malefic) placed in the tenth house is in the house of its accidental dignity, and although this placement may indicate delay, it also indicates ultimate success (should other factors support this interpretation) in one’s profession.
a part of the earth’s surface characterized by its elevation in relation to surrounding areas (for example, the Valdai Hills, the Central Russian Uplands). Convention-ally, an elevation is defined as an area with an absolute height of over 200 m and is contrasted to lowlands.
a term used in classical dance. Elevation, as defined by A. Ia. Vaganova, consists of two concepts: elevation proper (the height of a jump) and ballon (the ability to maintain a pose as if suspended in the air).
ii. The angle in the vertical plane between an object and the natural horizon. See angle of elevation.
