Introduction The modern professional surveyor must be competent in all aspects of surveying measurements such as height differences, linear distances, horizontal and vertical angle measurements and combinations thereof which form the fundamental observations used to Three data files (filename.txt) are supplied together with some brief notes on the operation of the program. This work presents basic methods in least squares adjustment computation. A survey station is said to be weight constrained if the coordinates of the station are associated with some standard deviations or some uncertainty. In practice such adjustment is performed using commercial software. ‘Least squares’ is a powerful statistical technique that may be used for ‘adjusting’ or estimating the coordinates in survey control networks. These methods are first principles’ technique, observation equations and condition equations techniques. references on least squares and geodetic surveying, but there is one in particular that we have found very comprehensive and well written: Adjustment Computations by Charles Ghilani ([1]). This note primarily describes the mathematics of least squares regression analysis as it is often used in geodesy including land surveying and satellite based positioning applications.

A simple numerical example is used to elucidate these basic methods. For example, the force of a spring linearly depends on the displacement of the spring: y = kx (here y is the force, x is the displacement of the spring from rest, and k is the spring constant). After the adjustment has been completed, a green circle with a "check mark" will be displayed.

Introduction The modern professional surveyor must be competent in all aspects of surveying measurements such as height differences, linear distances, horizontal and vertical angle measurements and combinations thereof which form the fundamental observations used to Three data files (filename.txt) are supplied together with some brief notes on the operation of the program. This work presents basic methods in least squares adjustment computation. A survey station is said to be weight constrained if the coordinates of the station are associated with some standard deviations or some uncertainty. In practice such adjustment is performed using commercial software. ‘Least squares’ is a powerful statistical technique that may be used for ‘adjusting’ or estimating the coordinates in survey control networks. These methods are first principles’ technique, observation equations and condition equations techniques. references on least squares and geodetic surveying, but there is one in particular that we have found very comprehensive and well written: Adjustment Computations by Charles Ghilani ([1]). This note primarily describes the mathematics of least squares regression analysis as it is often used in geodesy including land surveying and satellite based positioning applications.
