the height of anything above a given planetary reference plane, especially above sea level on earth.
extent or distance upward; height.
Astronomy. the angular distance of a heavenly body above the horizon.
the perpendicular distance from the vertex of a figure to the side opposite the vertex.
the line through the vertex of a figure perpendicular to the base.
Usually, altitudes. a high place or region:

Kipps, I say, felt himself a creature of outer darkness, an inexcusable intruder in an altitudinous world.

the vertical height of an object above some chosen level, esp above sea level; elevation
(geometry) the perpendicular distance from the vertex to the base of a geometrical figure or solid
(astronomy, nautical) Also called elevation. the angular distance of a celestial body from the horizon measured along the vertical circle passing through the body Compare azimuth (sense 1)
(surveying) the angle of elevation of a point above the horizontal plane of the observer
(often pl) a high place or region
late 14c., from Latin altitudinem (nominative altitudo) “height, altitude,” from altus “high” (see old).
The height of an object or structure above a reference level, usually above sea level or the Earth’s surface.
Astronomy The position of a celestial object above an observer’s horizon, measured in degrees along a line between the horizon (0°) and the zenith (90°). Unlike declination and celestial latitude—the corresponding points in other celestial coordinate systems—the altitude of star or other celestial object is dependent on an observer’s geographic location and changes steadily as the sky passes overhead due to the rotation of the Earth.

Mathematics The perpendicular distance from the base of a geometric figure, such as a triangle, to the opposite vertex, side, or surface.
