alidade[edit | edit source]
A stationary instrument, mounted on a stand, that measures the angle subtended at the stand by the horizon and an object in space.
The clinometer is a portable form of alidade frequently used with a ceiling projector to determine the height of clouds. An alidade usually measures the elevation angle only; a theodolite measures azimuth as well.
