The Plane Table Alidade was used as the sighting Instrument in the production of historical manual hand drawn maps. A Plane Table Board mounted on a tripod is levelled and the Alidade is placed on the table with the vanes perpendicular to the it. Each sighting vane has a central thread lined up on the target and the angle to that target point is then drawn on the map sheet using the beveled fiducial edge.

Plane table Surveying is a relatively portable and inexpensive method and was used extensively before the advent of sophisticated surveying instruments.
