Please allow me to share as shown in this image the ability of Least Squares Method of finding best fit solution for a data reduction process where linear approach (compass or transit rule) is surely to fail. The power and elegance the Least Squares Method provides enable you to adjust any configuration of control network as you wish. As shown in the figure, traverse adjustment is possible considering the constraints provided by the cross ties. Local to grid transformation and vice versa is done automatically. Great, great tool. A must for every surveyor.
