Altitudinous

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.
geometry.

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, alt-tudes. a high place or region:
mountain alt-tudes.
high or important position, rank, etc.
historical examples

kipps, i say, felt himself a creature of outer darkness, an inexcusable intruder in an alt-tudinous world.
kipps h. g. wells

noun
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 p-ssing 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
n.

late 14c., from latin alt-tudinem (nominative alt-tudo) “height, alt-tude,” from altus “high” (see old).
alt-tude
(āl’tĭ-td’)

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 lat-tude—the corresponding points in other celestial coordinate systems—the alt-tude of star or other celestial object is dependent on an observer’s geographic location and changes steadily as the sky p-sses overhead due to the rotation of the earth. see more at altazimuth coordinate system.

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