Exercise 3: Performing Least Squares Analysis
In this exercise, you will reduce the survey information using the least squares
adjustment method.
The least squares method calculates the most probable value for each
observation. The values are calculated by adjusting each of the observations
simultaneously so that the sum of the squares of the residuals (the difference
between measured and adjusted observations) is at a minimum.
For more information, see the AutoCAD Civil 3D Help topic Least Squares
Analysis.
This exercise continues from
