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.

“The stern hand of fate has scourged us to an elevation where we can see the great everlasting things which matter for a nationthe 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 (18631945)
“All our lives we fought against exalting the individual, against the elevation of the single person, and long ago we were over and done with the business of a hero, and here it comes up again: the glorification of one personality. This is not good at all. I am just like everybody else.”
—Vladimir Ilyich Lenin (18701924)
“The ability to secure an independent livelihood and honorable employ suited to her education and capacities is the only true foundation of the social elevation of woman, even in the very highest classes of society. While she continues to be educated only to be somebodys wife, and is left without any aim in life till that somebody either in love, or in pity, or in selfish regard at last grants her the opportunity, she can never be truly independent.”
—Catherine E. Beecher (18001878)
