The alhidade (or alidade) is not a true angle measuring instrument but rather a drawing tool allowing horizontal angles to be directly plotted in the field on e.g. a plane table. As most alhidades also have a vertical circle to measure height differences (and sometimes a tachymeter to measure distances) they are included into the angle measuring instruments.
