Abstract
This paper describes how the equivalent of a least‐squares adjustment of a level or traverse net may be obtained by electrical measurements in an analogous electrical net. The lengths of the survey lines are replaced by proportional electrical resistances; the survey closures are replaced by proportional small dc voltages; the adjustment corrections are read as electrical potentials at the various junction points. The resistances, power units, and junction jacks are mounted on a panel, and are interconnected by jumpers. The closure and correction voltages are read with a special type feed‐back voltmeter.
