Elevation

Elevation

The elevation of a geographic location is its height above 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 system, vertical datum). Elevation, or geometric height, is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface.

Famous quotes containing the word elevation:

    The stern hand of fate has scourged us to an elevation where we can see the great everlasting things which matter for a nation—the great peaks we had forgotten, of Honour, Duty, Patriotism, and, clad in glittering white, the great pinnacle of Sacrifice pointing like a rugged finger to Heaven.
    David Lloyd George (1863–1945)

    It was not till the middle of the second dance, when, from some pauses in the movement wherein they all seemed to look up, I fancied I could distinguish an elevation of spirit different from that which is the cause or the effect of simple jollity.—In a word, I thought I beheld Religion mixing in the dance.
    Laurence Sterne (1713–1768)

    Give the slave the least elevation of religious sentiment, and he is not slave: you are the slave: he not only in his humility feels his superiority, feels that much deplored condition of his to be a fading trifle, but he makes you feel it too. He is the master.
    Ralph Waldo Emerson (1803–1882)
