The Adjustment of a Level Net
George H. Dell · Transactions of the American Society of Civil Engineers · 1936
Two closely related methods of obtaining a “least squares” adjustment of the closing errors in a level net are described in this paper. The first method involves the writing, by inspection, of the appropriate normal equations and their subsequent solution by a process of converging increments; the second utilizes the principle of successive distributions, and is suggested by the Cross method of moment distribution.
